Photosynthesis and Cellular Respiration

Thanks to photosynthesis, planting trees will give us more oxygen. Trees may also help cool the Earth. HOW?

• By providing shade

• by absorbing the sun's energy, reducing heat in the atmosphere

• by adding oxygen which cools the atmosphere

• by removing CO₂ --less CO₂ means less trapped heat
