Answer 1

Answer:

option C

Explanation:

Plants may serve as starting point when observing the carbon cycle. they undergo a process called photosynthesis that enables them to absorb and utilize carbon dioxide from the atmosphere and combine it with water. in the presence of the energy of the Sun absorbed by chlorophyll in plants, they are able to synthesize sugars and oxygen molecules. They play a huge in keeping the air clean with the carbon becoming a part of the plant. Plants and other organisms that die and become buried may be converted into fossil fuels made of carbon like coal and oil over millions of years. when these are then burnt by humans, most carbon then return to the atmosphere as carbondioxide.
