Biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.

He process by which green plants and some other organisms use sunlight to make sugar from carbon dioxide and water.

When an organism cannot make its own sugars, it eats the tissue of another living or recently living organism.

Reaction that happens in basically all cells on Earth. Breaks up sugars and stores their energy in ATP, the molecule that all cells use for energy.

The end of the life of an organism

The process of burning something. The rapid chemical combination of a substance with oxygen, involving the rapid release of energy from the substance.

To make a solution by mixing with a liquid.

Living or once living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Ex. animals, birds, plants, fungi

Non living physical and chemical elements in the ecosystem. Abiotic resources are usually obtained from the lithosphere, atmosphere, and hydrosphere. Ex. water, air, soil, sunlight, and minerals.

Organisms that consume and breakdown dead organic matter. Heterotrophs.

Organisms which make their own food. Autotrophs

Organisms must obtain food from another organism. Heterotrophs Ex. animals, mammals, reptiles, amphibians, fish, bird
