What are the average temperatures of coral reefs and how do they impact the health and survival of marine ecosystems?

The average temperatures of coral reefs typically range from 73 to 84 degrees Fahrenheit. When temperatures rise above normal levels, it can cause coral bleaching, which weakens the corals and makes them more susceptible to diseases. This can lead to a decline in biodiversity and the overall health of marine ecosystems, impacting the survival of various species that rely on coral reefs for food and shelter.
