This document defines and provides examples of predators and prey. It explains that predators are animals that hunt and eat other animals, and have adaptations like sharp teeth and claws to help them catch prey. Prey are the animals that are hunted and eaten, and have adaptations like camouflage and living in groups for protection. The document discusses how the populations of predators and prey are interconnected, as increases or decreases in one will affect the other. It provides examples of predator and prey adaptations, and has students draw their own designs of a super predator and prey.
Lesson 5 predator and prey
- 1. Predators and Prey Target To understand the terms predator and prey.
- 2. Starter • Discuss with the person next to you what the words below mean – Predator – Prey
- 3. Predators • A predator is… • ….an animal that kills and eats other animals • Some examples of predators are…..
- 4. Prey • A prey is… • …...an animal that is killed and eaten (by a predator) • Some examples or prey are ……
- 7. Adaptations • Predators and prey have different adaptations • Can you think of any?
- 8. Adaptations of predators and prey Predators Reason Prey Reason Forward facing eyes Eyes facing sideways Sharp teeth Large ears Good Eyesight Travel in herds May hunt in packs Camouflage Fast runner May hide in burrows Sharp claws or beak Good sense of smell Sees prey well Grip prey See prey Better chance of catch Catch prey Hold prey See predator Hear predator Less chance of being caught Hard to see Difficult to find Smells predator
- 9. Homework task • Design a super predator and a super prey – draw your own design.

- 11. Feeding Types We can group animals together in many ways. One way that we can group them together is in the way that they feed. Consumers cannot make their own food. They must consume other organisms. Organisms may be producers. Producers make their own food.
- 13. Consumers Consumers can be grouped into different types: Carnivores These consumers eat other consumers or we might say they eat animals. Herbivores These consumers eat producers or plants and bacteria. Omnivores These consumers eat both other consumers and producers. So we might say they eat animals and plants. A bit like us!
- 17. Food Chains Food chains show us what is eaten by what. Look at the food chain below: grass rabbit hawk The shows the direction of energy flow in the chain. We can imagine that the arrow means ‘eaten by’, so energy is transferred in the direction of the arrow. So this food chain says: Note that food chains always start with a producer. If this is a plant it can be any parts of the plant , such as the seeds, fruits, leaves or even dead leaves. Grass is eaten by the rabbit, which is eaten by a hawk.
- 18. Draw four different food chains using the following as guidelines: Food Chains a) One of your food chains must occur in the forest b) One of you food chains must occur in the ocean c) One of your food chains must have four organisms in it d) One of your food chains must end with you!
- 19. Ranking Consumers We can use a food chain to group organisms in another way: seaweed limpet crayfish human Producer These organisms make their own food. Primary consumer This is an organism that eats producers. Secondary consumer This is an organism that eats primary consumers. Tertiary consumer This is an organism that eats secondary consumers. They are sometimes called the Top carnivore.
- 20. Numbers • Numbers of predators are affected by the number of prey and numbers of prey are affected by the number of predators • Why might this be?
- 21. Learning Objectives By the end of the lesson you should: • Know that predators and prey have different features • Understand that animals are adapted to eat the food they do • Be able to identify animals as predators or prey from their characteristics
