Carbon Cycle

All organisms require energy to maintain life The primary form of cellular energy is in ATP

adenosine triphosphate adenosine diphosphate -- carrier

Carbon Cycle

ATP is generated in a process called cellular respiration

Cellular respiration requires glucose molecules (a carbohydrate commonly called sugar)

C6H12O6

Carbon Cycle

Glucose is an organic compound, which means it contains carbon

Glucose must be made by organisms Organisms that make glucose are called

autotrophs (auto = self; troph = nourishment) Autotroph means self-feeding, or an organism

that can make its own food Autotrophs are called producers because they

produce their own food
