With the algae gone, the.
             coral skeleton is visible and eventually it dies. Died corals lead further on to the death of the reef. .
             There are four environmental factors that effect their growth: temperature, salinity, water.
             depth, and wave action. These factors exposes the reef to changes in the environment very easily.
             especially since it is located so close to shore. This also makes it hard for all of the species which.
             use the coral reef to survive. Coral reefs are home to perhaps one-fourth of all marine species. This in.
