In the darkness of the deep ocean, some organisms produce light through a process called

Answer: Bioluminescence.

Explanation:

Bioluminescence is the phenomena of production of light by living organisms.

This phenomenon is very common in deep sea oceans because at the depth of the ocean it is very dark and it helps the organisms to survive in the following ways :

1. It helps to attract prey.

2. It helps to confuse the predator.

3. To camouflage.

4. For communication.

5. To generate warning signals.

6. For illuminating the water column.
