      Introduction to food chains

      Lesson details

      Learning outcome

      I can order different plants and animals in a simple food chain.

      Key learning points

      1. Animals need food from plants and other animals to stay alive.
      2. A food chain is used to show the order in which living things depend on each other for food.
      3. A food chain begins with a plant.

      Keywords

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

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

      • Living - Something that is living is alive. It can grow, reproduce, move, feed and get rid of waste material.

      • Food chain - A food chain shows the order in which living things depend on each other for food.

      Common misconception

      Pupils may think that the arrows in the food chain mean "eats".

      Explain that the arrows in a food chain mean "is food for". Provide pupils with lots of opportunities to use this language.

      Teacher tip

      Provide lots of opportunities for the pupils to use "is food for" each time they look at a food chain. This will help them to position the arrows in food chains correctly.
