  • How do living organisms return carbon to the atmosphere in the carbon cycle?
    decomposition and respiration
  • How are burning of fossil fuels and volcanic eruptions similar with respect to their effects on the carbon cycle?
    Both add carbon to the atmosphere.
  • Carbon is used by plants during
    photosynthesis
  • one way that carbon enters the atmosphere
    Vehicle emissions/Exhaust, respiration, decomposition

  • Why is the carbon cycle important?
    It continuously reuses and recycles carbon in the ecosystem, enables energy flow throgh ecosystem, maintains the correct concentration of CO2 in atmosphere
  • How does the carbon in grass become part of a lion?
    The carbon ends up in the lion's food chain.
  • In what process is Carbon transformed into chemical energy?
    photosynthesis
  • Which one of these does not add CO2 to the atmosphere? (cooking with gas-planting trees-burning wood-riding in a bus)
    planting trees
  • How are fossil fuels related to the Carbon cycle?
    Dead plants filled with carbon can become fossil fuels
  • kenapa air laut terasa asin?
    karena ikan keringatan dikejar nelayan
  • What does not produce carbon dioxide? (Burning Fossil Fuels/Animal respiration/Photosynthesis/Plants decaying)
    Photosynthesis
  • Combustion is another word for
    burning
  • In the carbon cycle, producers take in the gas
    CO2
  • In the food web, which organisms release the carbon from dead things back into the environment?
    decomposers
  • one way humans can affect the carbon cycle
    Exhalation of carbon dioxide,
