Explanation:

• A population is a group of the same species living in a specific area. Since cottonball marsh pupfish live only in Cottonball Marsh, they form a population.
• A community is made up of all the different populations in an area. The pupfish interact with other species (like algae, seed shrimp, snails as food sources and birds, crayfish, bullfrogs as predators), so they are part of a community.
• An ecosystem includes all the living organisms (like the pupfish and other species) and the non - living environment (like the salty water, temperature - varying water in Cottonball Marsh). So the pupfish are part of an ecosystem.

Answer:

a population, part of a community, part of an ecosystem
