Flashcards
Photosynthesis
Photosynthesis
The process by which plants and other photosynthetic organisms convert atmospheric carbon dioxide (COâ‚‚) into organic carbon compounds, storing it in their tissues.
Respiration
Respiration
The process by which plants and animals release carbon dioxide (COâ‚‚) back into the atmosphere by breaking down organic matter for energy.
Decomposition
Decomposition
The breakdown of dead plants and animals by decomposers like bacteria and fungi, releasing carbon back into the soil and atmosphere.

Study Notes
Carbon Cycle Overview
- Carbon dioxide (COâ‚‚) is a primary form of atmospheric carbon.
- Photosynthesis converts atmospheric COâ‚‚ into organic compounds like sugars by plants, algae, and cyanobacteria.
- Carbon is stored in plant and animal tissues, moving through food chains.
- Respiration releases COâ‚‚ from both plants and animals.
- Decomposers release carbon back into the soil and atmosphere as COâ‚‚ or methane (CHâ‚„).
- Oceans absorb significant amounts of atmospheric COâ‚‚, supporting marine life's photosynthesis.
- Some ocean carbon is stored in deep ocean and marine sediments.
- Fossil fuels (coal, oil, natural gas) store carbon from decayed organisms over long periods.
- Burning fossil fuels releases stored carbon back into the atmosphere.
- Carbon is also stored in soil organic matter from plant roots, plant remains, and animal remains.
- Deforestation, agriculture, and industrial processes greatly influence the carbon cycle.
- Human activities, especially burning fossil fuels, significantly raise atmospheric COâ‚‚ levels, affecting the climate.
