Read the paragraph then answer the question:

Answer 1

Answer:

(5) If the coral dies, the reef becomes bare rock and sand no longer full of life.

Explanation:

The atmosphere is a part of coral reef because a large population of organisms lives in these coral reefs. It provides habitat to the biosphere of the  ocean as well as oxygen to the marine organisms. It can greatly affected with the increase concentration of carbondioxide due to acidification of water that kills the algae that is lives on the surface of these coral reef. So if these algae die due to lowering of pH, a large portion of marine organisms also removed from the environment due to unavailability of suitable environmental conditions.
