A biological species I would think.
they are also called unicellular organisms.
Any organism that is too small to be seen by the naked eye must be seen through a microscope. These small organisms are called microorganisms. Bacteria and spermatozoa are examples of microorganisms that we can only view through a microscope.
asexual reproduction only requires one male or female.
Multicellular organisms whose cells have nuclei but don't have cell walls are called anamalia cells
A living organism that consists of only one cell is called a unicellular organism. Some examples include bacteria, algae, and protozoa.
emus will not mate with humans they can only mate with their own kind
Monogamy is what having only one mate for life is called.
Mating in organisms can depend on various factors, such as mate choice, availability, and behavior. While some organisms may mate randomly, others exhibit specific preferences related to phenotype, genotype, or other characteristics that can influence the selection of a mate. Overall, mating behaviors can be influenced by a combination of genetic, environmental, and behavioral factors.
You can. You just have to wash your hands after your done.
Probably, but they wouldn't because birds are instinctively drawn to mate only with their own kind.
The taxon that includes only organisms that can successfully interbreed is called a species. Members of the same species are able to mate and produce viable, fertile offspring.

Herbivores
No cells are unicellular, only organisms can be unicellular.
they are also called unicellular organisms.
because they are very tiny organisms only seen by a microscope.
