Photosynthesis is the process by which autotrophs take in susbstances from the outside and convert take insubstances from the outside and convert them into stored formes of energy .the materials is taken in the form of carbon dioxide and water which is converted into carbohydrates in the presence of sunlight chlorophyll . The carbohydrates which are not used immediately are stores in the form of starch , which serves as the internal energy reserve to be used as and when required by the plant . The complex substances have to be broken down into simpler ones before they can be used for the unkeep and growth of the body . Heterotrophs depend for energy on :

The energy which we obtain from the sun is called solar energy or radiant energy. The sun's energy is stored in coal, natural gas, water and wind. Coal, oil, and natural gas are known as fossil fuels. Fossil fuels were formed over millions of years ago when the remains and fossils of prehistoric plants and animals sank to the bottom of swamps and oceans. These animal and plant remain were slowly covered and crushed by layers of rock, mud, sand, and water. The pressure of all those layers caused the plants and animals to break down and change into coal, oil and natural gas. We use the energy in these fossil fuels to make electricity. As of the year 2019, most of the energy we use comes from fossil fuels. However, fossil fuels are known as non-renewable sources of energy. They cannot be used over and over again. This means that one day they will run out! The energy source that uses collectors to heat water or air in buildings is
