Question

Describe the oxygen-carbon cycle and the role that plants play in this cycle?

Answer 1

Carbon dioxide is an end product in organisms that obtain energy from breaking down sugars, fats and amino acids with oxygen as part of their metabolism, in a process known as cellular respiration. This includes all plants, animals, many fungi and some bacteria. In higher animals, the carbon dioxide travels in the blood from the body's tissues to the lungs where it is exhaled. In plants using photosyIn nature, free oxygen is produced by the light-driven splitting of water during oxygenic photosynthesis. Green algae and cyanobacteria in marine environments provide about 70% of the free oxygen produced on earth and the rest is produced by terrestrial plantsnthesis, carbon dioxide is absorbed from the atmosphere.

Answer 2

plants take in carbon dioxide. release oxygen humans breath oxygen exhale carbon dioxide.
