Answer

Brief Explanations:

A population consists of individuals of the same species. The passage lists multiple species (Pacific blue mussels, black leather chitons, black oystercatchers), so they cannot form a single population. A community includes all living organisms in an area, which these species are part of. An ecosystem includes both biotic (living) and abiotic (non-living) components; since they are living organisms in a tide pool ecosystem, they are part of the ecosystem.

Answer:

B. part of a community, C. part of an ecosystem
