What is the most widespread organism on Earth?

Over the past five decades, the human population has doubled to nearly 8 billion people, but we occupy only 0.03% of the Earth's land area.

the Species diversity It refers to the total number of individuals of a given species in a given area. A species is considered common if it has one High population compared to the size of the area you inhabit We take.

It may also include other measures of the performance of animals, plants, or other life forms in an area, such as: b. Population density, number of breeding pairs and even biomass. It should be noted that Absolute species diversity differs from relative species diversity Differs from.

Absolute Species abundance back to The total number of individuals of a species in a given areawhile the Relative species abundance the The proportion of individuals of a species within the larger biological community count. Relative species diversity also measures the evenness of the total population of a community distributed among species.

The most common species in the world

the Oceans It makes up about 70% of the Earth's surface. However, large portions of them suffer from infertility Less biodiversity than Earth. However, the most biologically rich area on Earth's surface is a very thin layer compared to the oceans.

Therefore it is not surprising that The most common organism on Earth is a very small marine bacterium Named Candidatus Pelagibacter ubique he. It was only discovered in 2002 and does not have a name yet. In bacteriology the word is Candida A term that stands for “filter rate”.

The number of individuals of this species on Earth is greater than the number of stars in the universe.

Refers to species and others that have been discovered and given an informal name but that do not yet meet the requirements for an official name under International Code of Bacterial Nomenclature I have fulfilled. There are about 2 x 1028 Individuals from Pelagbacter is everywhere In the surface waters of temperate oceans.

For comparison: there are about 1021 Stars in all galaxies of the visible universe. This means that the number of this type of bacteria in the Earth's oceans is about 10 million times greater than the number of stars in the universe. Pelagbacter is everywhere Not only is it ubiquitous, it is also fascinating in its role in understanding life's limitations.

Pelagbacter And his relatives live in environments where Food is scarce, at concentrations approaching the minimum suitable for life. Scientists think so Pelagbacter is everywhere They have adapted to these conditions by simplifying their genomes and cellular structure Doing only the most important jobs of life.

In other words: These organisms simply liveThis allows them to be abundant in nutrient-poor “marine deserts” in the ocean. If one understands the nature of such an extreme being, one can Experts are learning more about the evolution of life Experienced on our planet and perhaps elsewhere in the universe.
