The diagram illustrates part of the carbon cycle.

Question

A fawn eating grass.
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.

Answer 1

The best description of the diagram is:

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

In this context, the fawn (which is a consumer) is eating grass (which is a producer), thus obtaining carbon from the organic molecules present in the grass.
