What is not alive in a coral reef?
A coral reef is an underwater ecosystem. It’s home to thousands of plant and animal species, to living and nonliving things, that all depend on each other. Nonliving things include the air, water, sunlight, soil, and minerals that animals, plants, bacteria, and other living things need to survive.

When a coral bleaches, it is not dead. Corals can survive a bleaching event, but they are under more stress and are subject to mortality.
