Flashcards
Carbon Cycle
Carbon Cycle
The continuous movement of carbon between the atmosphere, oceans, land, and living organisms.
Photosynthesis
Photosynthesis
Process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Respiration
Respiration
A process in living organisms involving the production of energy, typically with the intake of oxygen and the release of carbon dioxide from the oxidation of complex organic substances.
