The fuel of all Ecosystems is… THE SUN!!

Photosynthesis Sunlight energy is taken in by plants along with carbon dioxide and water, and converted into oxygen, and glucose Glucose is chemical energy we use as our fuel

Cellular Respiration Organisms use glucose for fuel and oxygen to breath We change this into carbon dioxide and water

You can’t have one without the other They work together! You can’t have one without the other Photosynthesis: Sun energy + CO2 + H2O  O2 + glucose Cellular Respiration: Glucose + O2  CO2 + H2O + energy
