What bones contribute to the formation of the orbit?

There is no data to show but there would definitely be a decrease in the population of the other organisms in lower trophic level (sea otter).

Explanation:

This question involves an aquatic food chain involving organisms like clams, sea stars, sea otters, and sharks. In this question, the shark appears to occupy the highest trophic level i.e. tertiary consumer. Ideally, as the food chain progresses from the lowest to highest trophic level, the population of each organism decreases.

However, an increase in the population of sharks will mean more mouths to feed on other consumers. Hence, causing a decrease in the population of other organisms in lower trophic level especially the organism that occupies the secondary consumer trophic level.
