In the deep waters of the ocean, coral reefs are found in abundance. Algae live on these coral reefs, providing nutrition and producing pigments that give color to the corals. The corals offer shelter to the algae. So, they share a association. Climate change has led to increased temperatures and has caused the corals to throw away the algae living inside them. This action causes the corals to be bleached because of a lack of pigment. This change will lead to a decrease in the coral growth, reduced fecundity and can cause death of corals.
