Answer:
B It helps maintain a level of carbon in the atmosphere that is neither too hot nor too cold.
Step-by-step explanation:
The carbon cycle is an important natural phenomenon without which life on earth would not be possible. It is the circulation of carbon molecules from atmosphere to organisms and substances then to atmosphere again.
The carbon cycle helps in maintaining a level of carbon in the atmosphere that is neither too hot nor too cold. When the balance of this cycle is disrupted, several climatic disruptions may occur such as global warming or extreme weather conditions.
This is why excess release of carbon into the atmosphere due of pollution causes global warming while decrease in carbon concentration in the atmosphere may cause extreme cold weather conditions.
