    • What is the main focus of the video discussed in the study material?
      The carbon cycle
    • Why is nutrient recycling important in ecology?
      It is the way elements are continuously exchanged between living and non-living parts of the ecosystem
    • Which two cycles are specifically mentioned for the course?
      Nitrogen and carbon cycles
    • What is the carbon cycle?
      It is the continual recycling of carbon for reuse
    • Why is the carbon cycle necessary?
      Because there is a limited supply of carbon that must be constantly recycled
    • What is the main source of carbon in the carbon cycle?
      The atmosphere
    • What happens to carbon dioxide during photosynthesis?

      It is converted into the carbohydrate glucose
    • How does carbon move through the food chain?
      Carbon is passed along the food chain as animals eat plants and other animals
    • What role do decomposers play in the carbon cycle?
      They break down organic matter containing carbon and return it to the environment
    • What is a consequence of incomplete decomposition in the carbon cycle?
      It can lead to the formation of fossil fuels
    • How is carbon released back into the atmosphere through respiration?
      Both plants and animals respire, returning carbon as carbon dioxide
