Question

read the passage. then answer the question below.

at 2,500 meters deep, an ocean vent at the bottom of the eastern pacific is in complete darkness. the vent releases hot water full of sulfur into the sea. the deep - ocean vent is home to a diverse group of organisms.

species such as giant tube worms grow to be 2 meters long. snails crawl on the outside of the tube worms. both the giant tube worms and the snails are hunted by pink vent fish, a species of deep - sea predator.

at a deep - ocean vent in the eastern pacific, the giant tube worms make up which of the following? select all that apply.

a population
part of a community
part of an ecosystem

Explanation:

1. Population: A population is a group of individuals of the same species living in a particular area. The giant tube worms at the deep - ocean vent are of the same species, so they form a population.
2. Part of a community: A community consists of all the different populations of organisms that live and interact in the same area. The giant tube worms interact with other species like snails and pink vent fish at the vent, so they are part of the community.
3. Part of an ecosystem: An ecosystem includes all the living organisms (community) in an area as well as the non - living components of their environment (like the hot, sulfur - rich water, the ocean vent structure, etc.). The giant tube worms, along with other organisms and the non - living environment at the vent, form an ecosystem, so they are part of an ecosystem.

Answer:

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