Photosynthesis

Photosynthesis, the process whereby the green pigment in plants (chlorophyll) traps energy from the sun, is responsible for the maintenance of all life on the planet, whether plant or animal. Animals are maintained by eating either plants or other animals that are nourished by plants. Life on earth is made possible by the sun. All oxygen in the atmosphere was put there by photosynthesis. All energy stored in coal and oil was supplied by photosynthesis. Obviously, photosynthesis is a topic worthy of attention.
