Living organisms have basic needs. Plants need air, water, nutrients, sunlight, and space to grow. Animals need air, food, water, and shelter.
Living organisms depend on each other and on their environments, or habitats, to meet their needs for survival. We call this interdependence.
A food chain is one way to show interdependence. A food chain shows the energy transfer from one organism to another. It begins with what gets eaten and continues the flow of energy with arrows pointing to what eats it.
See if you can build a food chain. Be sure to record each food chain in your notebook. Click the picture to identify the living organisms in a woodland environment and then build a food chain.
