Autotrophs - Organisms that make their own food/ energy.
Heterotrophs - Organisms theat obtain energy from the foods they consume.
Autotrophs use energy for photosynthesis, cellular respiration. Heterotrophs use energy to live, to hunt, and to reproduce.
Cells they get energy by breaking down food molecules to release, the stored chemical energy.
Photosynthesis- A chemical reaction that requires the energy of sunlight to convert water and carbon dioxide into glucose and oxygen. Cellular Respiration -A chemical reaction that releases energy by breaking down glucose in the presence of oxygen.
