The main characteristic of a carbon sink is that a. it emits no carbon b. it absorbs no carbon c. it emits more carbon than it absorbs d. it absorbs more carbon than it emits select the best answer from the choices provided

The correct answer is D. It absorbs more carbon than it emits. It is basically like a giant storage or a giant container for carbon that is used to remove excess CO2 from air. The process which is called carbon sequestration is very useful in preventing things like global warming and the greenhouse gasses effect. The less carbon it emits the better.

Explanation:

d. it absorbs more carbon than it emits.

Explanation:

The carbon sinks can be define as the natural reservoir such as plants and the entire diversity of forests which can absorb the carbon dioxide from the atmosphere more than the release of carbon dioxide into the atmosphere. The process by which the carbon dioxide removed from the atmosphere is called as carbon sequestration.

The forests absorb the carbon more as compared to it's emission by the process like respiration, decomposition of the dead plant matter and other biological processes.
