Worksheet Overview

In this activity, we will look at longer food chains.

You'll need to spot which living thing in each chain is the producer, consumer, predator or prey.


Look at the key terms below. It's really important you understand what they mean.

1) Predator = an animal that hunts and kills other animals to eat. They're also called carnivores.

2) Prey = an animal that's caught and killed by other animals to be eaten.

3) Producer = an organism that makes its own food. Plants are producers because they make their own food.

4) Consumer = an animal that eats plants or other animals. Consumers can't make their own food.

5) Herbivore = an animal that only eats plants.

6) Carnivore = an animal that eats other animals. They're also called predators.


Top tip: animals can be primary consumers or secondary consumers. Do you know the difference?


Let's look at this food chain:

 Grass  Grasshopper  Toad  Snake  Hawk


The grass is the producer which is what food chains usually start with.

The grasshopper is a primary consumer and herbivore because it only eats plants.

The toad, snake and hawk are all secondary consumers because they eat other animals. This means they are also carnivores because they eat meat and predators.


This is a lot of information but don't worry!

We'll put it to the test together now so that you feel super confident.

Over to you.
