Heterotrophs, Autotrophs & ATP

Heterotrophs

Organisms that eat a food source they do not make and must hunt for energy.

Autotrophs

Organisms that make their own food, typically through photosynthesis or chemosynthesis.

Cellular respiration

The process by which heterotrophs break down glucose into ATP energy.

Photosynthesis

The process by which autotrophs take in CO2 and H2O to make glucose and proteins.

Chemosynthesis

A process by which some organisms make food by combining chemicals.

ATP (Adenosine Triphosphate)

A molecule that transfers energy from the breakdown of food molecules to cell processes.

Carnivore

A type of heterotroph that eats other animals.

Herbivore

A type of heterotroph that eats plants.

Omnivore

A type of heterotroph that eats both plants and animals.

ADP (Adenosine Diphosphate)

A molecule formed from ATP after energy is released for cellular work.
