Final answer:
The carbon cycle involves biotic processes such as photosynthesis and respiration, and abiotic processes such as fossil fuel combustion and weathering. The oxygen cycle includes biotic processes like photosynthesis and respiration, and abiotic processes like diffusion and dissolution. The nitrogen cycle involves biotic processes such as nitrogen fixation and denitrification, and abiotic processes such as lightning and decomposition.
Step-by-step explanation:
In the carbon cycle, biotic processes include photosynthesis, respiration, and decomposition. For example, plants take in carbon dioxide during photosynthesis and release oxygen. Abiotic processes in the carbon cycle include fossil fuel combustion, weathering of rocks, and volcanic activity.
In the oxygen cycle, biotic processes involve the production of oxygen during photosynthesis and the consumption of oxygen during respiration. Abiotic processes include the diffusion of oxygen through the atmosphere and the dissolution of oxygen in water bodies.
In the nitrogen cycle, biotic processes include nitrogen fixation, nitrification, and denitrification. For example, certain bacteria in the soil convert atmospheric nitrogen into a form that plants can use. Abiotic processes in the nitrogen cycle include lightning, volcanic activity, and the decomposition of organic matter.
