Outline the process of the Carbon Cycle.
Bond [772]

Answer:

Carbon Cycle Definition

Carbon cycle is the process where carbon compounds are interchanged among the biosphere, geosphere, pedosphere, hydrosphere, and atmosphere of the earth.

Carbon Cycle Steps

Following are the major steps involved in the process of the carbon cycle:

Carbon present in the atmosphere is absorbed by plants for photosynthesis.

These plants are then consumed by animals and carbon gets bioaccumulated into their bodies.

These animals and plants eventually die, and upon decomposing, carbon is released back into the atmosphere.

Some of the carbon that is not released back into the atmosphere eventually become fossil fuels.

These fossil fuels are then used for man-made activities, which pumps more carbon back into the atmosphere.

Hope it helps!!!
