General KnowledgeBiology
- AA group of organisms of one species, living in the same area at the same time.
- BA group of organisms of one species living in different areas during different seasons.
- CA unit consisting of biotic and abiotic components.
- DA group of organisms of more than one species, living in the same area at the same time.
Explanation
In ecology a population is a group of organisms of one species living in the same area at the same time, sharing a common gene pool through interbreeding. A group of several species together is a community (option D), and a unit of biotic plus abiotic components is an ecosystem (option C). Organisms of one species scattered across areas and seasons do not form a single population.
