Water & Carbon Cycle

Cards (3)

  • How does CO2 enter and leave the environment
    • Enters; Photosynthesis
    • Leaves; Respiration
  • What is the process of the carbon cycle?
    • Carbon is removed from the air by green plants and algae via photosynthesis. They use the carbon to make carbs, protein and fats. When they are eaten, carbon is moved up the food chain
    • Carbon is returned to the atmosphere when organisms respire. Decomposers also respire when they return mineral ions to the cell
    • Carbon is also returned to the air when fossil fuels are burned as they contain carbon from photosynthesis
  • What is the process of the water cycle?
    • Transpiration/Suns energy causes water from sea to evaporate and form water vapour
    • Water vapour condenses into a cloud
    • Water is returned to land by precipitation which then flows to lakes to provide water for animals
    • This then runs into sea and the cycle begins again
