the process in which plants and some other organisms use the energy in sunlight to make food

Photosynthesis

the process that cells go through to create energy, usually involves exchanging two gases—oxygen and carbon dioxide

cellular respiration

naturally occurring substances (like hydrogen, oxygen, and nitrogen) that also contain carbon, found in the cells of living things

organic compounds

the process by which the body breaks down food so that it can be used for energy

digestion

Blood cells and oxygen travel throughout the body to reach all of the body's organs.

circulation

Plants use the energy of the sun to change water and carbon dioxide into this sugar

glucose

a nutrient used by animals

protein

Glucose used by plants for energy

sugar

the body's main source of energy: sugars and starches

carbohydrate

biological molecule that is insoluble in water; fatty acid

lipid

the form of energy your body cells use to do their work, also called cellular respiration (adenosine triphosphate)

ATP
