Autotrophs
Organisms such as plants that make their own food
Heterotrophs
Organisms that cannot make their own food, such as humans
Cellular Respiration
A chemical process that uses oxygen to convert the chemical energy stored in organic molecules into another form of chemical energy, ATP
Photosynthesis
Plants use the sun's energy to convert water and carbon dioxide into sugars
Inputs - Outputs (Photosynthesis)
CO2 + H2O - C6H12O6 + O2
Inputs - Outputs (Cellular Respiration)
C6H12O6 + O2 - ATP + H2O + CO2
