Question

in the mediterranean sea, an artificial reef is made from concrete saved from construction projects. the marine biologists who designed the reef did not want the heavy concrete to sink into soft mud. so, they put the reef in an area where the seafloor is hard and rocky. the large concrete structure creates a habitat. clams and barnacles grow on the concrete. shrimp and crabs can hide from predators in the reef. the reef also attracts fish species such as dover sole and black scorpionfish, which eat the smaller organisms. on an artificial reef in the mediterranean sea, the rocky bottom, the dover sole, and the shrimp make up which of the following? select all that apply. a population part of a community part of an ecosystem

Explanation:

A population is a group of the same species. Here, Dover sole, shrimp are different species, so they don't form a population. A community is all the living organisms in an area, so Dover sole, shrimp are part of the community. An ecosystem includes both living (biotic) and non - living (abiotic) components. The rocky bottom is non - living and together with the living organisms like Dover sole and shrimp, they are part of an ecosystem.

Answer:

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