1. TOPIC 2 CYCLES IN THE ENVIRONMENT

2. Energy in the environment is passed through food chains/webs
It is NOT recycled
Matter in the environment is also passed through food chains/webs
It IS recycled
Why is this important?
What types of matter are cycled?
Carbon, water, pollution

3. 1. The Carbon Cycle Where is carbon found? ALL living things Minerals
Fossil fuels
Air (carbon dioxide)

4. Lab Activity 3: TellTale Snails

5. Plants use the carbon found in carbon dioxide for photosynthesis
Carbon is found in the sugar plants make
Herbivores eat plants and get their carbon from the plants
Carnivores eat other consumers and get their carbon from those animals
Animals release carbon as carbon dioxide when they exhale

6. The Carbon Cycle Where else is carbon found?

7. Fossil fuels
Decomposing plant and animal materials are put under great pressure underground
Still contains the carbon that was in the organisms
Burning fossil fuels releases carbon dioxide into the air
