Question 33 • Biology

What would most likely happen to the carbon cycle if there were no more plants on Earth?

Answer
A
Animals would consume more carbon.
B
Carbon would build up in the atmosphere.
C
Animals would perform more photosynthesis.
D
More carbon would be released from fossil fuels.

Explanation

Plants take in carbon dioxide from the atmosphere during photosynthesis and store carbon in their tissues. Without plants, that carbon-removal process would stop, while animals and other organisms would continue releasing carbon through respiration and decomposition. As a result, carbon would build up in the atmosphere; animals cannot replace plants by performing photosynthesis.
