Answer:
To create feeling or empathy for the animals of the tide pool
Explanation:
The author is trying to create a sense of empathy towards the animals that live in tide pools. The purpose is probably to make a comparison or to complete a point because the reader is asked to consider the plight of the animals.
Then, the reader is informed of the conditions in the tide pools and several of the dangers that the resident animals must face. The combination of these two elements seems like a call for sympathy.
