Populations
The biosphere part surrounding organisms is the environment. They have complete interaction and formation within the environment which results to the study of ecology.
Subspecies are the smaller groupings within a species. It is below the rank of species. Subspecies usually are interbreed and isolated organisms.
Single nucleotide polymorphisms (SNPs) and short tandem repeats (STRs)
Pollination is required for sex. Sex is very adaptive and useful to spread genes around for pretty much all lifeforms and keep the diversity up within a species. It takes place because sex is useful for organisms and that's plant sex.
Groups of similar organisms within a species are called populations. Populations consist of individuals of the same species that can interbreed and share a common geographical location.
Separating organisms into unicellular and multicellular categories might not be useful because some unicellular organisms may be more closely related to multicellular organisms than to other unicellular ones. Additionally, this classification overlooks important differences within each group, such as varying levels of complexity or ancestral relationships. Therefore, grouping solely based on cell number could oversimplify the diversity and evolutionary history of organisms.

Populations
the range of organisms present in a particular ecological community or system. It can be measured by the numbers and types of different species, or the genetic variations within and between species.
The Doushantuo rock formation in China encompasses fossils. The fossils within the Doushantuo rock formations have been found to contain organisms that share traits with Amoebas.
