      Lesson details

      Learning outcome

      I can use a simple food chain to show how animals and plants depend on each other for food.

      Key learning points

      1. The basic needs of animals for survival are water, food and air.
      2. Animals need food from plants and other animals to survive.
      3. A food chain is used to show the order in which living things depend on each other for food.
      4. A food chain can be drawn as a simple scientific diagram. The arrows represent 'is food for'.

      Keywords

      • Animal - An animal is a living thing which moves and eats other animals or plants.

      • Basic needs - A living thing's basic needs are what they need to be able to survive.

      • Plant - A plant is a living thing that often has a stem, roots, and leaves.

      • Depend - To depend on is to rely upon.

      • Food chain - A food chain shows how living things depend on each other for food.

      Common misconception

      Pupils often think the arrow in a food chain means “eats” and also that arrows should be drawn from predator to prey (rather than prey to predator).

      This lesson reinforces the fact the the arrow in a food chain can be interpreted to mean 'is food for'.

      Teacher tip

      Encourage pupils to read the food chains aloud, and use the phrase 'is food for' in place of the arrow in each example.

      Equipment

      Pupils may wish to use books or the internet to help with a range of ideas for Practice Task B.
