Detailed explanation-1: -Carbon Cycle Steps 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.

Detailed explanation-2: -Photosynthesis, Decomposition, Respiration and Combustion. Carbon cycles from the atmosphere into plants and living things. For example, carbon is a pollutant in the atmosphere as carbon dioxide.

Detailed explanation-3: -The process of respiration produces energy for organisms by combining glucose with oxygen from the air. During cellular respiration, glucose and oxygen are changed into energy and carbon dioxide. Therefore, carbon dioxide is released into the atmosphere during the process of cellular respiration.
