How does ocean warming primarily affect coral reefs?

• By increasing the growth rate of corals

• By causing more fish to inhabit the reefs

• By leading to coral bleaching

• By decreasing the salinity of ocean water

What is coral bleaching?

• The process by which corals turn white due to the growth of algae

• The process by which corals expel the algae living in their tissues, causing them to turn white

• The process by which corals change color to adapt to warmer temperatures

• The process by which corals harden and become fossilized

What role do algae play in the health of coral reefs before bleaching occurs?

• They compete with corals for sunlight, weakening them

• They provide corals with essential nutrients through photosynthesis

• They erode the coral structures, leading to their collapse

• They attract predators that feed on corals

Why is ocean warming considered a significant threat to marine ecosystems?

• It increases the oxygen levels in the water, leading to overgrowth of algae.

• It decreases the amount of sunlight penetrating the ocean surface.

• It can lead to changes in marine biodiversity and the loss of corals and other species.

• It causes an increase in the salinity of ocean water, making it uninhabitable.
