Answer:
According to the biological species concept, a species os composed of populations in which members mate with each other and produce fertile offspring. Members of diffent species cannot interbreed successfully due to reproductively isolating mechanism. Futhermore, this species concept mainly is used for sympatric species because it is difficult to apply to geographically separated populations. In contrast, the ecological species concept suggests that separation of species is maintained by natural selection in which each distinct species has adapted to its own specific part of the environmental.
