Final answer:
The collection of interacting populations within the same environment is known as a community. The correct answer is c) Community, which is different from an ecosystem, biosphere, and habitat.
Step-by-step explanation:
The interaction of various populations within a particular environment is defined as a community. These interacting populations include various species such as plants, insects, and microbial life that inhabit the same area at a given time. When considering the options a) Ecosystem b) Biosphere c) Community d) Habitat, the correct answer to the question 'This is a collection of interacting populations within the same environment.' is c) Community.
An ecosystem includes not only the biotic components, which make up the community, but also the abiotic, nonliving parts of the environment such as soil nutrients and water. Biosphere is the broadest level, encompassing all ecosystems and representing all zones of life on Earth. Lastly, a habitat is the physical environment where a species or a population lives.
