This group of organisms would be called a Community.
When a group of organisms can interbreed they are considered a species. Humans can interbreed and produce other humans because they are the same species.
Species.
Populations of the same species can successfully interbreed. Humans are a good example of this happening in the real world.
Organisms that can interbreed are all members of the same species if their offspring are viable (can themselves breed).
a group of organisms that can reproduce only among themselves and that are usually contained in a geographic region.

Species
A population is a group of organisms of the same species that live in a specific geographical area. In ecology, the population of a certain species in a certain area is estimated using the Lincoln Index.
Members of a group that have the ability to interbreed and produce fertile offspring are called "species". This is the zoolocigal definition and name for the group.
species
If a group of organisms cannot be interbreed, and create fertile offspring, thent hey are separate species. If the can be interbreed, and the offspring can also interbreed, then they are different sub-species, or phases of the same species.
birds willinbreed with each other but so did dinosaurs back in the day on a small island in the tropics about 30 million years ago
