Quick Answer. Plants absorb energy from the sun and use photosynthesis to make sugars. Animals have mitochondria that use the sugars provided by plants to produce their own cellular energy. Plants that produce their own food, and food for other plants and animals using photosynthesis, are called autotrophs.
Organisms obtain energy in different ways. But all energy traces down from the sun. Most plants get energy by absorbing sunlight in their chloroplasts by the means of photosynthesis, however there are some carnivorous plants, such as the Venus Flytrap. Herbivores eat the plants and get energy from them. Then carnivores eat the herbivores. This is the food chain.
