Study Notes

Photosynthesis

Process where plants harness solar energy to transform water and carbon dioxide into sugars.
Essential for producing glucose, which serves as food for plants and foundational energy for ecosystems.

Respiration

Biological process converting energy stored in glucose into usable energy for cellular functions.
Involves breaking down glucose in the presence of oxygen, releasing carbon dioxide as a byproduct.

Exchange

Involves the transfer of carbon among Earth's spheres: biosphere (living matter), atmosphere (air), hydrosphere (water), and geosphere (earth).
Critical for maintaining the balance of carbon in the environment and supporting various life forms.

Sedimentation

Process where soil particles and decomposed organic material build up in layers, either on land or in water bodies.
Plays a significant role in forming sedimentary rock, contributing to geological processes over time.

Extraction

Refers to the ability of plants to draw carbon from the atmosphere.
This process is vital for reducing atmospheric carbon levels and contributing to plant growth.

Combustion

Chemical reaction where organic materials are burned in the presence of oxygen, producing carbon dioxide, water, and energy.
Major factor in the carbon cycle, releasing carbon stored in fossil fuels and biomass back into the atmosphere.
