100

Coral reefs supply this resource to communities on the coastline

What is food?

100

Ocean currents transport this to new reef sites

What is offspring?

100

As oceans absorb more CO2, the pH level decreases, making the ocean this

What is more acidic?

100

Less oxygen in the ocean does this to coral reefs

What is suffocate / kill?

200

Coral reefs protect the land from these

What are natural disasters?

What is microscopic algae?

200

An increase in nitrogen from the runoff fertilizers from farms and lawns and the toxins from the sewage from industries and communities lead to this

What is a large growth of algae?

300

The percent of wave energy taken in by coral reefs

What is 97%?

300

Larger fish produce this

When the current is stronger, it carries this to the surface

What is colder water?

300

400

When the ocean temperatures get this, algae leaves the coral

What is warm?

400

This causes coral to expel their microscopic algae

What is a pollutant?

500

The force created by water

What is wave energy?

500

Fish urine contains this element

500

Coral does this when the water gets too warm and the coral loses its color

What is bleaching?

500

When corals can't do this, it makes them more prone to weather damage and disease
