Which is the relationship between animals and plants in the carbon cycle? <br>​
enyata [817]

Answer:

Animals release carbon dioxide into the air, and plants take it in.

Explanation:

The existence of plants and animals on the planet is important in maintaining life. Animals release carbon dioxide as waste through the respiratory system. The carbon dioxide that is released is then taken in by plants, which they use to produce their own food through a process called photosynthesis. The by product of that process is oxygen which is released in the atmosphere and animals take it in.
