Presentation transcript:

Carbon compounds are contained in every living organism. We can follow carbon as it moves through living things, into the Earth’s atmosphere and back. This is called the Carbon Cycle.

Plants absorb carbon dioxide from the atmosphere and turn it into glucose using photosynthesis Animals eat the plants for the energy in glucose and then release carbon dioxide back into the atmosphere.
