Discuss how forests act as carbon sinks.

They undergo photosynthesis which makes the carbon dioxide to be used rather than produced.

Explanation:

Hello,

Forests are widely known as the "Earth's lungs" due to the photosynthesis that vegetable life constantly perform as the carbon dioxide that is in the environment is used by them to produce energy, glucose and oxygen considering such metabolic pathway. Now, forest act as carbon sinks as the proportion between carbon dioxide consumers to producers is by far greater than 1 as long as there are more plants that use higher amounts of carbon dioxide than those that are released during the respiration of animals or any other natural process producing carbon dioxide.

Best regards.

false

because it does not have the potential to be entirely used up
