6.5.4 - Recycling within ecosystems ( CARBON CYCLE )

Cards (5)

  • define decomposers
    organisms that feed on organic matter and turn them into inorganic stuff
    • what are decomposers described as?
    saprotrophs
  • what do saprotrophs do?
    they secrete enzymes out of their body to their surroundings, digest them then absorb it back into their body ( extended digestion)
  • define detritivore
    organism that feeds on organic matter by internal digestion, which increases its surface area to speed up the process of decomposition
  • draw the carbon cycle and give me a brief explanation
    1. co2 in air
    2. plants : photosynthesis, respiration, feeding to animals
    3. animals: respiration, feeding (from plants), decomposers to dead matter
    4. decomposers to dead matter
    5. dead matter: decomposition( from animals + plants, decomposers, formation of fossil fuels).
    6. fossil fuels: combustion to air
