Energy Pathways Assignment Diagram an energy pathway for each of the paragraphs below. Be sure to label the types of energy in each pathway. 1. Energy travels from the sun to the Earth as light. When sunlight reaches the earth, some of the light is reflected back into space, but most is absorbed by the earth and changed into heat. Greenhouse gases in the atmosphere trap the heat energy around the earth, slowing its escape into space. 2. Some of the light energy that comes to the earth is absorbed by plants and converted to chemical energy stored in the chemical bonds of plant sugars. The chemical energy in the plants can then become food for animals. The animals use the chemical energy in their food to live, and move. This energy eventually leaves the animal’s body as heat. When the animal dies, decomposers eat the dead animal and release more heat. 3. Sunlight is absorbed by land plants or ocean plants and is changed to chemical energy. These plants sometimes become buried in the earth for millions of years. Here they might become fossil fuels such as coal, oil, or natural gas. When people burn fossil fuels (like gasoline in our cars), most of the energy is released as heat. Greenhouse gases in the atmosphere slow the escape of heat into space.
