Question

The biological 'job' of shrimp in the ocean is to feed on organic matter such as dead sea grass, bacteria, and dead fish. On land, cockroaches feed on dead leaves, garbage, and other refuse. Which is the most accurate statement about shrimp and cockroaches?

A) Both animals are detrivores, and they fill the same niche in different environments.
B) Both animals are detrivores, but they fill different niches in different environments.
C) The shrimp is a decomposer, while the cockroach is a detrivore. They have the same
niche in different environments.
D) The shrimp is a detrivore, while the cockroach is a decomposer. They have different
niches in different environments.

Answer 1

Both the shrimps and the cockroaches are considered to be as scavengers at any point because they feed on dead organisms. Therefore the most accurate statement among the two organisms is "Both animals are detrivores, and they fill the same niche in different environments."

Answer 2

Answer:

A) Both animals are detrivores, and they fill the same niche in different environments.

Explanation:

Niche of an organism refers to its habitat, activity role and functional position within system. Detritivores are the organisms that feed on dead and decaying organic matter and serve to release the nutrients back in the environment. Since both shrimp and cockroach feed on dead and decaying organic matter, both are detritivorous. Being found in different habitat, they fulfill the same niche (same functional role, that is, the role of detritivore) in different environments.
