Energy and Biomass

HideShow resource information

Energy and biomass.

Biomass is the total quantity or weight of organisms in a given area or volume.

Light energy pours out continuosly on the surface of the earth. Plants and algae absorb light energy using chlorofyll for photosynthesis. During this process, some of the light energy is transferred to chemical energy. This energy is stored in the substance that make up cells of the plants and algae.

Respiration is 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.


In the Carbon Cycle:

  • Carbon dioxide is removed from the environment by green plants and algae during photosynthesis.
  • The carbon from the carbon dioxide is used to make carbohydrates, fats and proteins, which make up the body of plants and algae.
  • When green plants and algae respire, some of this carbon becomes carbon dioxide and is released into the atmosphere.
  • When green plants and algae are eaten by animals and these animals
