Answer 2

Answer:

The answer is (c) Carbon cycle

Explanation:

The carbon cycle depicts the movement of carbon on Earth in both its elemental and mixed forms.

The carbon cycle describes the exchange of carbon compounds between the earth's biosphere, geosphere, pedosphere, hydrosphere, and atmosphere.

• Carbon dioxide is the most common kind of carbon in the atmosphere.
• Carbon is released into the atmosphere through both natural and man-made activities, such as the burning of fossil fuels.

• Photosynthesis is the process through which plants absorb carbon dioxide and convert it into carbohydrates.

                    $CO_2 +H_2O +energy$  → $(CH_2O)_n +O_2$

• Carbon molecules are passed down the food chain from producers to consumers.
• A considerable amount of carbon is emitted into the atmosphere as carbon dioxide as a result of the respiratory activity of producers and consumers.

• Decomposers are responsible for eating dead organisms and releasing carbon from their bodies into the atmosphere and the equation is $(CH_2O)_n +O_2$  →  $CO_2 +H_2O$
