Species:

A

A group of individuals that look similar and are able to interbreed and produce fertile offspring

A species can be identified if two individuals can breed and produce offspring

If a horse and a donkey were to breed they would produce a mule as offspring, mules are infertile because their “parents” are of different species.

For two different species ti interbreed they have to be kinda similar like have similar structures, diets etc. Like a lion and springbok cant breed because they are too different.
