Where is the distribution of reef-building corals limited to?

The tropics and subtropics.

What needs to be low for light penetration?

Water depth in order for photosynthesis to be carried out

What is the importance of salinity in coral reef ecosystems?

Salinity must be regulated to avoid osmotic problems in coral and zooxanthellae.

How does water clarity affect coral reefs?

High turbidity prevents light penetration

What temperature conditions are optimal for coral and zooxanthellae?

Corals and zooxanthellae thrive in warm temperatures, which are optimum for their survival.

How do coral reefs contribute to marine biodiversity?
