•Flow of energy Flow of energy begins with the begins with the SUN and SUN and PhotosynthesisPhotosynthesis

6CO2 + 6H2O + sunlight & chlorophyll C6H12O6 + 6O2

PhotosynthesisPhotosynthesis•Chemical reaction where green Chemical reaction where green plants use plants use water & carbon dioxidewater & carbon dioxide to to store the store the sun’s energy in glucosesun’s energy in glucose

•ENERGY is stored in glucoseENERGY is stored in glucose

•Glucose is stored as starch in plantsGlucose is stored as starch in plants

Organisms that Organisms that can make glucose can make glucose

during during photosynthesis photosynthesis

are calledare called PRODUCERS.


10

Producers Producers use use most of the most of the energy they energy they

makemake for for themselves.themselves.

Producers use Producers use cellular cellular

CELLULAR CELLULAR RESPIRATION RESPIRATION is is

the chemical the chemical reaction that reaction that releases the releases the

energy in energy in glucoseglucose..

6O2 + C6H12O6 --> 6H2O + 6CO2 + energy
