Detailed explanation-1: -Carbon moves through ecosystems in two cycles that overlap. In the biotic cycle, it moves between living things and the air. In the abiotic cycle, it moves between the air, ground, and oceans. By burning fossil fuels, humans have increased the amount of carbon dioxide in the air.

Detailed explanation-2: -The carbon cycle is a fundamental component of the biogeochemical dynamics of Earth. Carbon is exchanged and cycled between atmosphere, ocean layers, land, and geosphere through processes such as photosynthesis, decomposition, respiration, and mineralization.

Detailed explanation-3: -The carbon cycle is the biogeochemical cycle in which carbon moves through the biotic and abiotic components of ecosystems.

Detailed explanation-4: -Photosynthesis by land plants, bacteria, and algae converts carbon dioxide or bicarbonate into organic molecules. Organic molecules made by photosynthesizers are passed through food chains, and cellular respiration converts the organic carbon back into carbon dioxide gas.
