  • ATP is
    A usable form of energy
  • What is the name for the process of burning fossil fuels that releases carbon into the atmosphere?
    combustion
  • How are fossil fuels formed?
    When decomposing organisms are exposed to pressure, high temperatures, and bacteria over hundreds of millions of years.
  • True or False: Carbon is only released from living organisms on land.
    False
  • The inputs of photosynthesis are:
    Carbon dioxide and Water
  • When organisms die, which members of the food chain break them down and return carbon to the soil?
    Decomposers
  • What necessary life process done by plants and animals releases carbon into the atmosphere?
    cellular respiration
  • A river would belong to which of Earth's spheres?
    Hydrosphere
  • Explain why deforestation leads to less oxygen production
    Trees produce oxygen through photosynthesis therefore chopping them down will decrease oxygen levels
  • Oxygen and Glucose are made during which chemical process
    Photosynthesis
  • Name the three types of fossil fuels
    Coal, oil, natural gas
  • True of False: Oceans can absorb carbon dioxide
    True
  • In what form does carbon exist in the atmosphere?
    carbon dioxide
  • Which sphere contains all living things on Earth?
    Biosphere
  • What process removes carbon from the atmosphere?
    photosynthesis
  • Carbon cycles through each environmental sphere. Give one example of a sphere in which carbon is found and explain how it enters that sphere.
    Atmosphere, biosphere, hydrosphere, geosphere
  • True or False: Plants do photosynthesis while animals do respiration
    False - plants do both!
