This response is important because it enables the plant to increase its intake of carbon dioxide. Carbon dioxide is an important gas,during the process of photosynthesis, where plants use energy from sunlight to make simple sugars and release oxygen. This is also a way of absorbing carbon dioxide (a green house gas) from the atmosphere thus reducing its amounts.
Answer:
A lot of carbon passes through the atmosphere and into the biosphere through the plants consuming it, or in other words, photosynthesis, and the plants waste is oxygen, which animals breathe and turn into carbon dioxide
TL;DR Plants enter carbon into the biosphere and animals release it into the atmosphere
