Accepted Answer

Many animals live in coral reefs, like fish, sea turtles, and crabs. Reefs provide food and a safe place to hide from predators.

Question 9

How do coral reefs help us?

Accepted Answer

Coral reefs give us food like fish and shellfish. They also help protect the shore by slowing down big waves before they reach the land.

Question 10

What is happening to coral reefs today?

Accepted Answer

Many coral reefs are in danger because the ocean is getting warmer and more polluted. This makes it hard for corals to grow and survive.

Question 11

Can people help save coral reefs?

Accepted Answer

Yes, people can help by reducing pollution and protecting the ocean. Scientists are also working on ways to grow new corals and fix damaged reefs.

Question 12

What is coral bleaching?

Accepted Answer

Coral bleaching happens when corals get too stressed, like when the water is too warm. They turn white because the algae that give them color leave or die.

Question 13

Do corals grow quickly?

Corals grow very slowly, often just a few centimeters a year. That's why it takes a long time for coral reefs to form.

Question 14

Are corals animals or plants?

Accepted Answer

Corals are animals, even though they sometimes look like plants. They are related to jellyfish and sea anemones.

Question 15

How do corals reproduce?

Question 16

What can hurt coral reefs?

Accepted Answer

Pollution, warm water, and too much fishing can all hurt coral reefs. These things can make it difficult for corals to grow and stay healthy.

Question 17

Why do corals need algae?

Accepted Answer

Corals need algae because they provide food for the corals through photosynthesis. In return, the corals give the algae a safe place to live.

Question 18

Accepted Answer

Coral reefs can recover from some damage if left alone. However, it takes a long time, and the reefs need clean water and healthy conditions to heal.

Question 19

How do scientists study coral reefs?

Accepted Answer

Scientists study coral reefs by diving or using underwater robots. They observe the corals and other animals, and sometimes they take small samples to study in labs.

Question 20
