Question

what is one of the roles coral reefs play in marine ecosystems? source of shelter and protection increase pollution deplete marine life decrease biodiversity

Explanation:

Coral reefs are complex marine structures. They have numerous small crevices, overhangs, and nooks. These physical features offer hiding spots for various marine organisms like small fish, invertebrates. This protection helps them avoid predators. Also, the reef structure can buffer against strong ocean currents and waves to some extent, providing a relatively safer environment. The other options are incorrect. Coral reefs do not increase pollution (they can be harmed by pollution), do not deplete marine life (they are habitats that support a large number of species), and do not decrease biodiversity (they are one of the most biodiverse marine ecosystems).

Answer:

source of shelter and protection
