A food chain shows how each living thing gets food, and how nutrients and energy are passed from creature to creature. Food chains begin with plant-life, and end with animal-life. Some animals eat plants, some animals eat other animals.
Every living organism needs energy to live. Plants get their energy from the Sun, some animals get their energy from eating plants, and other animals get energy from eating other animals. A food chain is a way of organizing living things by what they eat. It shows who's eating who. The arrows in a food chain show the flow of energy. Everything in the food chain is either a producer or a consumer.
