1. Photosynthesis and Respiration

2. Photosynthesis and Respiration in Ecosystems
Photosynthesis Involves:
INPUTS
PROCESSES
OUTPUTS

3. INPUTS
Sunlight
Carbon dioxide
Water

4. PROCESS Chlorophyll traps sunlight The energy splits water molecules
Combines the hydrogen liberated with carbon dioxide

5. OUTPUTS Glucose used as an energy source by the plant
Oxygen released to the atmosphere

6. Photosynthesis transformations
Light energy TO
Stored chemical energy

7. What does it do?
Powers the whole ecosystem

8. Producers are
The starting point of all energy available for an ecosystem

9. Respiration
The release of energy from glucose or other organic substances inside living cells

10. INPUTS Glucose and Oxygen Oxidation process in the cells
Release of energy for work and heat

11. Transformations
Stored chemical energy TO
Kinetic energy and Heat
