1. Day 4 Flow of Matter and Energy

2. Where does energy come from?

3. Cellular Respiration:
PS and CR cycle
Flow of Matter and Energy
Sun:
Light Energy
Photosynthesis:
Light Dependent and Calvin Cycle
In the Chloroplast
Water and Carbon Dioxide
Glucose (Sugar) and Oxygen
Cellular Respiration:
Krebs Cycle and Electron Transport Chain
In the Mitochondria
ATP:
Chemical Energy 86 87

4. Flow of Matter and Energy
Slide 1 of 3
Flow of Matter and Energy
EQ: How does matter flow between abiotic and biotic factors?
Decomposers (Bacteria)
Consumers/ Heterotrophs
Producers/ Autotrophs
Main Energy: Sunlight
10% moves to next level
(Q1)
(Q2)
10 calories
Energy 
100 calories
1,000 calories
The energy from the Sunlight is absorbed by Autotrophs producing Glucose through Photosynthesis
The energy from Glucose (Food) goes through Cellular Respiration or Fermentation to produce ATP.

5. Slide 2 of 3
Energy (Cont.)
Adenosine Tri-Phosphate: the usable energy of cells. A P P P
(Q3)
Living things need energy to survive.
Energy stored as ATP in cells.
Energy is released by breaking the chemical bond between the 2nd and 3rd phosphates.
Adenosine Di-Phosphate Adenosine Tri-Phosphate
Energy
Partially charged battery
Fully charged battery

6. Flow of Matter and Energy
Slide 3 of 3
Flow of Matter and Energy
Photosynthesis and Cellular Respiration have three important elements: Carbon, Hydrogen, and Oxygen
H2O Water (liquid)
CO Carbon Dioxide
O Oxygen (gas)
C6H12O6 Sugar/Glucose
There are more elements
and molecules involved,
but these are the main
molecules you’ll need to
learn.
