What are coral reefs?

Back

Coral reefs are underwater structures made from calcium carbonate secreted by corals. They provide habitat for many marine species.

Front

Why are coral reefs important?

Back

Coral reefs support a diverse range of marine life, providing food and shelter for many plants and animals.

Front

What is coral bleaching?

Back

Coral bleaching occurs when corals lose their color due to stress, often from increased water temperatures, leading to the expulsion of algae.

Front

What causes coral bleaching?

Back

Coral bleaching can be caused by climate change, pollution, and changes in water temperature.

Front

What are producers in an ecosystem?

Back

Producers are organisms that can make their own food, typically through photosynthesis, like plants and algae.

Front

What are consumers in an ecosystem?

Back

Consumers are organisms that cannot make their own food and rely on eating other organisms for energy.

Front

What role do concrete blocks play in coral reef restoration?

Back

Concrete blocks are used by scientists to create artificial reefs, providing a structure for corals to grow on.

Front

How do coral reefs benefit humans?

Back

Coral reefs provide food, protect coastlines from erosion, and support tourism and fishing industries.

Front

What is the relationship between coral and algae?

Back

Coral and algae have a symbiotic relationship where algae provide food for coral through photosynthesis, and coral provides a habitat for algae.

Front

What happens to marine life when coral reefs are damaged?

Back

When coral reefs are damaged, many marine species lose their habitat, leading to declines in biodiversity.
