Answer to Question 1

The sun produces enormous quantities of energy-some of it in the form of visible light, a tiny portion of which strikes Earth. Only about 1 part in 2,000 of the light that reaches Earth's surface is captured by organisms, but that small input of energy powers nearly all the growth and activity of living things on Earth's surface Light energy from the sun is trapped by chlorophyll in organisms called primary producers and changed into chemical energy. The chemical energy is used to build simple carbohydrates and other organic molecules-food-that is then used by the primary producer or eaten by animals called consumers. Because light energy is used to synthesize molecules rich in stored energy, the process is called photosynthesis. The stored energy is released when the food is used for growth, repair, movement, reproduction, and the other functions of organisms.
