Question

Describe carbon cycle with a well labelled diagram​

Answer 1

Carbon is an essential element in the bodies of living organisms.. Carbon dioxide CO2 from the atmosphere is taken up by photosynthetic organisms and used to make organic molecules, which travel through food chains......

Answer 2

The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.

• During this process, CO2 is converted to Glucose.
• Some amount of this Glucose is used for respiration by plants.
• The rest of it is converted to other carbohydrates and fats stored in various parts of plants.
• When animals eat plants these carbon-containing compounds are taken up by the animals and digested and absorbed.
• These are used by animals for respiration.
• Thus carbon in carbon dioxides in the atmosphere finds their way into animals.
• Metabolic degradation of these compounds especially during respiration releases CO2 into the air.
• Decomposition of dead bodies of animals and plants by bacteria also releases CO2 into the air.
• Thus the CO2 finds its own way into the bodies of animals and plants and back into the air.
