Carbon Cycle By: Hortencia Avila, Uriel Lopez, Jeremy Glick
2
Carbon Cycle Fourth most abundant element in universe
Building block of all living things Main Pathway– in and out of living matter Carbon Cycle
3
Carbon Cycle- Circulation of carbon through ecosystems Carbon- A non-metallic element found in coal, petroleum and natural gas. Major component of life. Soil Respiration- Carbohydrates are oxidized and returned to the air by soil microorganisms that decompose dead animals Key Terms
4
Key Terms Continued Atmosphere- layer of gasses
Fossil Fuels- Carbon-rich fuel from ancient animals and plants Photosynthesis- Energy (sun)+ Water+ Carbon dioxide Carbohydrates+ Oxygen Cellular Respiration- Glucose+ Oxygen CO2+ H20+ Energy (ATP) Decomposition- breakdown of matter by bacteria and fungi Key Terms Continued
5
Biological Importance of Carbon
All living organisms contain carbon CO2 is found in all living organisms Plants use carbon dioxide and water to form simple sugars (photosynthesis) Biological Importance of Carbon
6
Ecological Importance of Carbon
Carbon is needed for life Carbon dioxide is a greenhouse gas Carbon is necessary for life, but carbon dioxide can be harmful Ecological Importance of Carbon
