Question

In spite of breathing out carbon dioxide in a large amount and released by combsuion, the atmosphere has mere fraction of CO only. Why?

Answer 1

Answer:

C3 photosynthesis produces a three-carbon compound via the Calvin cycle while C4 photosynthesis makes an intermediate four-carbon compound that splits into a three-carbon compound for the Calvin cycle. Plants that use CAM photosynthesis gather sunlight during the day and fix carbon dioxide molecules at night.

Answer 2

Explanation:

Hey mate here ur answer

This is because there is a huge amount of plant diversity in the planet as compared to animals. Plants use the Co2 produced by the animals to synthesise their food (glucose) and release O2 . This is the reason why a little fraction of Co2 is present in the atmosphere as compared to O2 and other gases.
