  • Too much CO2 can make Earth _____.
    warmer
  • Name one clean technology shown in the video.
    Wind power (or solar cars / biogas / biofuels / algae / compost)
  • People who make new ideas are called _____.
    inventors
  • Cutting down forests is called what?
    Deforestation
  • Which star gives Earth its energy?
    The Sun
  • Plants turn sunlight and CO2 into what stored form of energy?
    Carbohydrates
  • Burning fossil fuels releases which gas back into the air?
    CO2
  • How does deforestation affect the balance of CO₂ in the atmosphere?
    Fewer trees mean less CO₂ is taken out of the air so CO₂ levels rise.
  • When animals eat plants our bodies turn the food into what?
    Energy
  • How do animals, including humans, move carbon through the food chain?
    They eat plants or other animals and release CO₂ through breathing and waste.
  • What is the name of the process plants use to make food?
    Photosynthesis
  • Explain how plants help reduce CO₂ in the air.
    (They take CO₂ from the air during photosynthesis and store it in their bodies.)
  • When animals eat plants, our bodies turn the food into what?
    Energy
  • Why is burning fossil fuels a problem for the carbon cycle?
    (It releases large amounts of stored CO₂ back into the atmosphere, adding more greenhouse gas.)
  • Why is burning fossil fuels a problem for the carbon cycle?
    It releases large amounts of stored CO₂ back into the atmosphere adding more greenhouse gas.
  • Cutting down many trees is called _____.
    deforestation
  • Suggest one everyday action people can take to help rebalance the carbon cycle.
    (Plant trees, use less energy, ride a bike instead of driving, recycle, etc.)
  • Pushing the boundaries of ideas and inventions is called what?
    Innovation

  • Humans breathe in oxygen and breathe out what?
    CO2
