The diagram illustrates part of the carbon cycle.

Which best describes the diagram?
A consumer is obtaining carbon by breathing it in from the atmosphere.
A consumer is obtaining carbon by absorbing it from the soil.
A consumer is obtaining carbon by eating carbon-based molecules stored in a producer.
A consumer is obtaining carbon by eating carbon-based molecules stored in a decomposer.

C. A consumer is obtaining carbon by eating carbon-based molecules stored in a producer.

Explanation:

Consumers are those organisms which feed on other organisms for getting energy. Plants produce carbon containing compounds such as glucose by using carbondioxode, water and solar energy in the process of photosynthesis. This glucose get by consumers after eating this plant and energy is released in the form of ATP from glucose in the process of cellular respiration. This energy is used by consumers in different activities.
