Question

read the passage. then answer the question below. a tide pool on the oregon coast tide pools on the oregon coast can experience large waves and strong currents. many tide pool organisms attach securely to the surrounding rocks to avoid being swept away. ochre sea stars make a sticky substance to help them hold onto the rocks. pacific blue mussels glue themselves to the rocks using structures called byssal threads. a black leather chiton sticks to a rock by creating suction with its strong muscular foot. black oystercatcher birds eat mussels and chitons. these birds are strong enough to pry animals off of the rocks. in a tide pool on the oregon coast, the pacific blue mussels, the black leather chitons, and the black oystercatchers make up which of the following? select all that apply. a population part of a community part of an ecosystem

Explanation:

A population consists of individuals of the same species. Here, we have multiple species (Pacific blue mussels, black leather chitons, black oystercatchers), so it's not a population. A community is all the populations (different species) in a given area. An ecosystem includes both the biotic (living organisms like these species) and abiotic (non - living, e.g., rocks, water in the tide pool) components. Since the question is about these organisms, they are part of a community (as multiple species) and part of an ecosystem (as they are living components of the tide - pool ecosystem).

Answer:

part of a community, part of an ecosystem
