Question

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 is not a population.
• A community is made up of all the different populations (species) in a particular area. These organisms are part of the community in the tide - pool.
• An ecosystem includes all the living organisms (like these species) and the non - living components (such as rocks, water, waves) of a particular area. So, they are part of an ecosystem.

Answer:

part of a community, part of an ecosystem
