Question

What is the next phase of the carbon cycle for the carbon source labeled C? (2 points) Label A shows a collection of coal, oil and gas. Label B shows a collection of trees and vegetation. Label C shows sky and open atmosphere.

Cellular respiration

Photosynthesis

Fossil fuels

Decomposition

Answer 1

It's Photosynthesis.

First I did Cellular respiration and got it wrong

Answer 2

Answer: Option A; cellular respiration

Step-by-step explanation: Since the arrow is towards open air, it will not be photosynthesis, as this process is associated with trees and vegetation, in Label B. So option B is incorrect. Option C is about fossil fuels which is labelled under A, so it is again incorrect answer. Decomposition of organic matter will either take place on land or in water. Thus, option D is also incorrect.

Since the CO2 released from respiration will add to the atmosphere, option A is correct answer.
