REACTIONS OF LIFE Water is involved in reactions of life: •Photosynthesis Carbon Dioxide + Water → Fuel + Oxygen 6CO2 (g) + 6H20 (g) → C6H12O6 (s) + 6O2 (g)
•Respiration Fuel + Oxygen → Carbon Dioxide + Water C6H12O6 (s) + 6O2 (g) → 6CO2 (g) + 6H20 (g)
THE WATER CYCLE Water – plants & animals: •Transport system for nutrients and soluble wastes. •System to transfer heat. •System to cool the body. Water and Climate: •Rain •Evaporation •Ground Water
