Animals eat plants and produce carbon dioxide and water. How do animals affect the amount of carbon in earth atmosphere

They increase the amount of carbon in the atmosphere

Explanation:

Carbon is usually introduced into the atmosphere in a gaseous form. The atmosphere is the gaseous envelope round the earth.

When animals respire, they take up food materials from plants and other sources. They then metabolically break it down.

Oxygen is needed for respiration and in turn, the waste product is usually carbon dioxide.

So, respiration by animals releases carbon dioxide as a by product.
