Plants provide energy to animals in their life processes by

The life process by which plants provide energy to animals is nutrition. Plants are nutritionally autotrophs. They synthesized their food through a process called photosynthesis. In this process,  plants use sunlight, carbon dioxide and water to produce glucose and oxygen is released as by-product. The glucose is stored as starch in plants. Animals eat plants to get energy as they are heterotrophs and cannot make their food.
