Reading Comprehension

Read the passage and answer the question.

Bioluminescence, the production of light by living organisms, is far more common in the deep ocean than on land. In the dark waters below the reach of sunlight, many creatures generate their own glow using a chemical reaction. Some fish use light to lure prey toward their mouths, while others flash to confuse predators or to signal potential mates. A few species even release clouds of glowing particles into the water, creating a distraction that allows them to escape. Because so little light penetrates these depths, the ability to make light offers a decisive survival advantage.
