Resource summary

Energy(biomass) in food chains
  1. Radiation from the sun is the source of energy for most communities of organisms
    1. green plants absorb small amounts of light energy and convert it to chemical energy during photosynthesis.
      1. Biomass at each stage can be drawn to scale in a pyramid of biomass
        1. Biomass typically reduces at each stage in a food chain
          1. materials + energy lost in organisms' waste materials
            1. energy transferred to surroundings for example through movement
              1. DECAY PROCESS
                1. living things remove materials from there environment whilst they live for example to have energy for growth and movement
                  1. These materials are returned to the environment through waste or deacay(once dead)
                    1. Decay is due to dead animal being broken down and digested by microorganisms rate of decay increases with temperature, moisture levels and AEROBIC CONDITIONS
                      1. The decay process releases substances plants need to grow
                        1. a stable community is where the processes that remove materials are balanced by processes which return them, materials are constantly cycled
        2. "total mass of organisms in a given space"
