What does the following diagram illustrate?

A food chain because the algae goes to the minnows then the minnows go to the salmon then the salmon goes to the bear :)

Corals that have a type of shell are probably more resistant to hurricane damage. An example of this type of coral is the star coral.

Explanation:

Some corals have a structure that surrounds them and provides protection against mechanical damage. This structure provides a type of "shell", which involves the colony of corals making it more resistant, than corals that do not have this structure, an example of coral that has this structure is called "star coral". As a result, these corals are more resistant to hurricane impact, with little or no damage.
