There’s no denying that we need energy from food to survive, but have you ever wondered how the energy gets in our food? Join this lesson to find out. Energy flows between living things in the form of a chain called a food chain. Human beings are at the top of a food chain mainly because we eat a variety of food and we are rarely eaten by other animals. Simply put, a food chain is a model that shows how energy flows between living things. A living organism can be a part of several food chains depending of its feeding pattern. In a habitat, all living organisms of a food chain interact to form a system. When living organisms interact with their non-living environment, they form an ecosystem.
