Protein

Used to build and heal tissue

Lipids (Fats)

Makes up tissue

Carbohydrates

3. All living things

Need energy

Organisms need energy to…

Grow, reproduce, remain healthy, and about everything

Autotrophs

Organisms that make their own food

Photosynthesis

Process where plants take energy and turn it into glucose using Carbon Dioxide and water

Heterotrophs
