Question

You are a molecule of carbon. Choose a starting point in the carbon cycle and describe the process you would go through to move through the entire cycle.

Answer 1

Answer: Part 1

In carbon cycle, carbon is mainly present in the form of carbondioxide gas. This carbondioxide is absorbed by the plants from the atmosphere and used as a raw material for the production of food materials such as glucose in the process of photosynthesis. When this food is eaten by living organisms, this food is used for the production of energy in the process of respiration which produces energy, water and carbondioxide. This carbondioxide is released in the atmosphere through breathing and the cycle is completed and starts again.

Carbon in carbon dioxide gas is taken in by plants for photosynthesis.

Plants turn the carbon atom into a carbohydrate.

An animal eats the plant and uses its carbohydrates for energy.

During respiration, the animal releases carbon dioxide back into the atmosphere.
