Which Biological Kingdom Comprises The Greatest Biomass On Earth

The 6 kingdoms of Classification in 3 minutes

Which of the five biological kingdoms – animalia, protista, plantera, monera, or fungi – has the largest biomass?

To clarify, if the biomass of every species in each of these kingdoms was added up, which kingdom would have the greatest sum?

  • 1$\begingroup$A really clear, well defined question with great biological significance. In a silly way, this number can help us quantify which is “winning”! Welcome to Bio.SE!$\endgroup$May 17, 2016 at 12:42

Probably Eukaryotes. Specifically, plants.

This is a very fundamental question of life that is often overlooked. It goes without saying that plants and animals are the strongest contenders. However bacteria may also rival them. Be aware though that this is a contentious claim given more thorough estimations that take into account fluctuations in bacterial presence. This EMBO Reports science and society article claims that plants account for 99% of Eukaryotic biomass.

For further reading the Wikipedia page on biomass doesn’t seem too shabby for more details on tonnage and methods of calculation.

Modern System Of Classification

A pattern of groups nested within groups was specified by Linnaeus’ classifications of plants and animals, and these patterns began to be represented as dendrograms of the animal and plant kingdoms toward the end of the 18th century, well before Charles Darwin’s On the Origin of Species was published. The pattern of the “Natural System” did not entail a generating process, such as evolution, but may have implied it, inspiring early transmutationist thinkers. Among early works exploring the idea of a transmutation of species were Erasmus Darwin‘s 1796 Zoönomia and Jean-Baptiste Lamarck‘s Philosophie Zoologique of 1809. The idea was popularized in the Anglophone world by the speculative but widely read Vestiges of the Natural History of Creation, published anonymously by Robert Chambers in 1844.

Cladistic classifications are compatible with traditional Linnean taxonomy and the Codes of Zoological and Botanical Nomenclature. An alternative system of nomenclature, the International Code of Phylogenetic Nomenclature or PhyloCode has been proposed, whose intent is to regulate the formal naming of clades. Linnaean ranks will be optional under the PhyloCode, which is intended to coexist with the current, rank-based codes. It remains to be seen whether the systematic community will adopt the PhyloCode or reject it in favor of the current systems of nomenclature that have been employed for over 250 years.

When Carl Linnaeus introduced the rank-based system of nomenclature into biology in 1735, the highest rank was given the name “kingdom” and was followed by four other main or principal ranks: class, order, genus and species. Later two further main ranks were introduced, making the sequence kingdom, phylum or division, class, order, family, genus and species. In 1990, the rank of domain was introduced above kingdom.

Prefixes can be added so subkingdom and infrakingdom are the two ranks immediately below kingdom. Superkingdom may be considered as an equivalent of domain or empire or as an independent rank between kingdom and domain or subdomain. In some classification systems the additional rank branch can be inserted between subkingdom and infrakingdom, e.g., Protostomia and Deuterostomia in the classification of Cavalier-Smith.

Taxonomy: The Science Of Classification

biological classification

Organisms were first classified by Aristotle, who lived in ancient Greece over 2,000 years ago. He divided all living things into two main groups: Plants and Animals. He sorted plants into smaller groups such as Small, Medium, and Large, and sorted animals into Land, Water, and Air. You can probably see that this system wasn’t very useful. In such a system, birds, bats and bumblebees were grouped together, simply because they all fly.

Much later, in 1758, a Swedish scientist named Carl Linnaeus developed a new way of organizing living things. If you think about where you go to school, a way of classifying with different levels, might be: District – School – Grade – Class – Student. Linnaeus’s classifying system had seven levels, starting with two broad groups he called “kingdoms“: Plantae and Animalia . He then used descending subgroups based on more specific characteristics. Linnaeus is called the “Father of Taxonomy” because we still use his classification and naming system today.

The classification categories look like this: Kingdom – Phylum – Class – Order – Family – Genus – Species

Humans are classified like this: Animalia – Chordata – Mammals – Primates – Hominids – Homo – Sapiens

This five-kingdom model is still used in some places. In 1990, many scientists agreed that kingdom Monera should be divided into Eubacteria and Archaea, making six kingdoms. Today, the exact way that kingdoms should be divided is still a matter of disagreement among some biologists.

What Is A Kingdom In Biology

The system of biological kingdoms is the way in which science classifies living things according to their ancestry over the course of evolution. This means that all the species that make up these five large groups – some recent theories split them further into six or even seven – have common ancestors and therefore share some of their genes and belong to the same family tree.

As well as the kingdoms of living things there are other taxonomic categories within the same classification system such as, for instance, domain, phylum, class, order, family, genus and species. They all follow a hierarchical order and are dependent on each other, so some divisions include others. In this way, the domain includes the kingdom, the kingdom the phylum, the phylum the class, and so on.

Characteristics Of The Six Kingdoms Of Organisms

From the tiniest bacterium to the largest blue whale, all living organisms are classified by their characteristics. The biologist Carolus Linnaeus first grouped organisms into two kingdoms, plants and animals, in the 1700s. However, advances in science such as the invention of powerful microscopes have increased the number of kingdoms. There are now six commonly accepted kingdoms. Each kingdom includes a set of organisms that share similar characteristics. The organisms in each Kingdom are considered biologically distinct from the others. The six Kingdoms are: Archaebacteria, Eubacteria, Fungi, Protista, Plants and Animals.

Interactions With Other Organisms

Six Kingdoms of Classification

The well-characterized interactions between archaea and other organisms are either mutual or commensal. There are no clear examples of known archaeal pathogens or parasites, but some species of methanogens have been suggested to be involved in infections in the mouth, and Nanoarchaeum equitans may be a parasite of another species of archaea, since it only survives and reproduces within the cells of the Crenarchaeon Ignicoccus hospitalis, and appears to offer no benefit to its host.


One well-understood example of mutualism is the interaction between protozoa and methanogenic archaea in the digestive tracts of animals that digest cellulose, such as ruminants and termites. In these anaerobic environments, protozoa break down plant cellulose to obtain energy. This process releases hydrogen as a waste product, but high levels of hydrogen reduce energy production. When methanogens convert hydrogen to methane, protozoa benefit from more energy.

In anaerobic protozoa, such as Plagiopyla frontata, archaea reside inside the protozoa and consume hydrogen produced in their hydrogenosomes. Archaea also associate with larger organisms. For example, the marine archaean Cenarchaeum symbiosum lives within the spongeAxinella mexicana.

What Are The Six Kingdoms Of Biology

SIX KINGDOMS OF BIOLOGY In this topic, we are going to know and identify the six kingdoms of biology.

In Biology, the organisms were classified into three domains: Bacteria , Archaea, and Eukarya.

It is then divided into six kingdoms, according to ThoughtCo, here are the following:

  • Archaebacteria
  • These are single-celled prokaryotes that were formerly thought to be bacteria. These fall under the Archaea domain. They also have a ribosomal RNA type.
  • Eubacteria
  • They are considered to be true bacteria and are classified under the Bacteria domain. They are main microscopic organisms that compose the human microbiota.
  • Protista
  • A very diverse group of organisms which have characteristics of animals, plants or fungi. These fall under the Eukarya domain.
  • Fungi
  • These include both unicellular and multicellular organisms. They are incapable of photosynthesis unlike plants. They are vital for recycling nutrients beck into the environment. These fall under the Eukarya domain.
  • Plantae
  • Commonly known as plants, these are extremely vital to all life on Earth since they provide oxygen, shelter, clothing, food, and medicine.
  • Animalia
  • Other Popular Subjects And Locations

    Plant KingdomThe plant kingdom is the second largest of all the kingdoms with more than 250,000 species. The plant kingdom includes all types of plants including mosses, flowering plants, and ferns. Species in the plant kingdom consist of complex cells and are multicellular. Species within this kingdom are also autotrophs, meaning that they produce their own food. Some examples of species within the plant kingdom include trees, flowers, and even fruits and vegetables.

    ArchaebacteriaThe archaebacteria kingdom is made up of single-celled organisms and the name of the kingdom means ancient bacteria. Scientists actually believe that members of the archaebacteria kingdom were among the first life forms on Earth billions of years ago. These species lack cell structure and their genetic material is not contained inside of a nucleus. The cells of archaebacteria are called prokaryotes. Archaebacteria are known to be found in extreme environments including those that are very hot, those with no oxygen, and those that are highly acidic. Archaebacteria are separated from eubacteria because their cell structure is so different.

    Archaea and bacteria have generally similar cell structure, but cell composition and organization set the archaea apart. Like bacteria, archaea lack interior membranes and organelles. Like bacteria, the cell membranes of archaea are usually bounded by a cell wall and they swim using one or more flagella. Structurally, archaea are most similar to gram-positive bacteria. Most have a single plasma membrane and cell wall, and lack a periplasmic space the exception to this general rule is Ignicoccus, which possess a particularly large periplasm that contains membrane-bound vesicles and is enclosed by an outer membrane.

    A Simple Explanation Of The Six Kingdoms Of Life For Kids

    There are many different kinds of living things or organisms on Earth. Scientists have grouped them together into kingdoms. These kingdoms are called:

    • Animalia
    • Protista

    The organisms in each kingdom are similar in certain ways.

    You are most familiar with the plant and animal kingdoms. As you can see, they are very diverse groupings. A blade of grass and a giant tree may seem very different, but both are still plants. Elephants and grasshoppers are very different, but both belong in the animal kingdom.

    Placing organisms into different groups is called taxonomy.

    Parasitism: Role As Pathogens

    Some protists are significant parasites of animals , plants or even of other protists. Protist pathogens share many metabolic pathways with their eukaryotic hosts. This makes therapeutic target development extremely difficult a drug that harms a protist parasite is also likely to harm its animal/plant host. A more thorough understanding of protist biology may allow these diseases to be treated more efficiently. For example, the apicoplast present in apicomplexans provides an attractive target for treating diseases caused by dangerous pathogens such as plasmodium.

    Recent papers have proposed the use of viruses to treat infections caused by protozoa.

    Researchers from the Agricultural Research Service are taking advantage of protists as pathogens to control red imported fire ant populations in Argentina. Spore-producing protists such as Kneallhazia solenopsae can reduce red fire ant populations by 53100%. Researchers have also been able to infect phorid fly parasitoids of the ant with the protist without harming the flies. This turns the flies into a vector that can spread the pathogenic protist between red fire ant colonies.

    Introduction: Features Of The Animal Kingdom

    Animal evolution began in the ocean over 600 million years ago with tiny creatures that probably do not resemble any living organism today. Since then, animals have evolved into a highly-diverse kingdom. Although over one million extant species of animals have been identified, scientists are continually discovering more species as they explore ecosystems around the world. The number of extant species is estimated to be between 3 and 30 million.

    But what is an animal? While we can easily identify dogs, birds, fish, spiders, and worms as animals, other organisms, such as corals and sponges, are not as easy to classify. Animals vary in complexity, from sea sponges to crickets to chimpanzees, and scientists are faced with the difficult task of classifying them within a unified system. They must identify traits that are common to all animals as well as traits that can be used to distinguish among related groups of animals. The animal classification system characterizes animals based on their anatomy, morphology, evolutionary history, features of embryological development, and genetic makeup. This classification scheme is constantly developing as new information about species arises. Understanding and classifying the great variety of living species help us better understand how to conserve the diversity of life on earth.

    The Six Kingdoms By Veritas Prep

    There are countless organisms in the world and the scientific classification system was put in place to group together species that share common characteristics. This classification system is rooted in the work of Carolus Linnaeus, who is known as the father of modern taxonomy. The scientific classification system in biology consists of seven different groups or rankings. These rankings include kingdom, phylum, class, order, family, genus, and species. When talking about scientific classification, one will notice that all of the scientific names and terms are written in Latin. The idea to use Latin belonged to Carolus Linnaeus, and the thought was that Latin terms would mean the same thing to scientists all around the world whereas common names are different in different languages and would cause confusion. This article will focus in the kingdom section of the scientific classification system. There are six kingdoms including plants, animals, fungi, protists, archaebacteria, and eubacteria.

    Animal KingdomThe animal kingdom is the largest of all of the six kingdoms and is made up or more than one million species. Members of the animal kingdom are characterized by their ability to obtain energy from eating food. All species in the animal kingdom are also multicellular and the cells of the species in this kingdom have a nucleus but no chloroplasts or cell wall. Examples of species within the animal kingdom would include all mammals, reptiles, birds, insects, and more.
