To answer the multiple-choice question, we first need to understand the definitions of the options provided:

1. **Biogeochemical cycle**: This term refers to the cycle of chemical elements and compounds between living organisms and the environment. It does not pertain to a grouping of organisms.

2. **Habitat**: This is a natural environment where an organism lives, but it does not specifically refer to interacting populations.

3. **Niche**: A niche is the role an organism plays in its environment, encompassing its habitat, resource use, and interactions with other organisms. However, it still does not refer to a collective group of populations.

4. **Community**: In ecology, a community refers to a group of different populations that live together in a defined area and interact with one another.

Given these definitions, the correct answer is:

### Final Answer
**community**
