What is the carbon cycle?
It describes how carbon is recycled in nature
1 of 14
What does photosynthesis do in the carbon cycle?
Removes carbon dioxide from the air
2 of 14
Why does carbon dioxide need to be returned to the atmosphere?
So the carbon dioxide can be used by plants in photosynthesis
3 of 14
What is the water cycle?
Describes how fresh water circulates between living organisms, rivers and the sea

What are predators?
