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
