Question

7. Which of the following are aspects of the niche of a crab?

Answer 1

Answer:

A crab lives in the intertidal zone.

A crab spends most of its time scavenging for food in the sand.

Explanation:

These tell us where a crab lives and where/how it feeds.

"A crab has an exoskeleton." is a true statement about the characteristics of a crab, but tells us nothing of its interaction with the environment so is not niche.

"A crab will avoid predators by quickly moving underneath an object to hide."

is a true statement, but is too general to identify a niche. Could be modified to cover niche if it said something like "A crab will avoid predators by quickly moving underneath an abandoned seashell or a coral rock to hide."
