Photosynthesis and Respiration

Photosynthesis and Respiration in Ecosystems Photosynthesis Involves: INPUTS PROCESSES OUTPUTS

INPUTS Sunlight Carbon dioxide Water

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

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

Photosynthesis transformations Light energy TO Stored chemical energy

What does it do? Powers the whole ecosystem

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

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

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

Transformations Stored chemical energy TO Kinetic energy and Heat
