Worksheet Overview

QUESTION 1 of 10

Where does your food come from?

For many of us the answer may well be "the supermarket!"

Actually, almost all of our food comes from plants and other animals. Animals such as sheep eat grass and other similar plants. When the sheep has grown to a suitable size, we kill the sheep and eat it. In the seas and oceans small fish such as mackerel are eaten by bigger fish such as trout. The trout might themselves be eaten by even bigger fish such as sharks, or they are caught by us for our food.

Food chains are very useful diagrams which show us the feeding patterns of different animals. We can read a food chain and understand not only what an animal feeds on to get its food, but also what other animals may eat that particular animal for food. 

The different plants and animals in a food chain are connected by arrows. The direction of the arrow shows us which animal is being eaten. The arrow always goes from the prey (the animal being eaten) to the predator (the animal that is eating). Food chains always start with plants. We call these plants producers

producer  prey  predator 

 

A simple food chain for the fish above would look like this:

Here is a very simple food chain.

grass  sheep human 

 

This food chain shows us that grass is eaten by sheep – and then sheep are eaten by humans. Sheep mostly eat grass.

Which other animal from the list also obtains most of its food by eating grass?

blackbird

cow

goldfish

squirrel

Humans eat sheep – we often call it lamb but you may have heard it being called mutton as well.

Which part of the sheep do we eat?

horn

meat

teeth

wool

Sheep only eat plants like grass. They do not eat meat.

Some humans also choose not to eat meat.

Complete this sentence.

People who only eat plants – and not meat – are known as _________________.

carnivores

herbivores

omnivores

vegetarians

Sometimes we can get more than one type of food product from an animal.

Think about cows.

Apart from meat, what other food products can we get from cows?

chocolate

milk

pasta

Lions live on the African savanna.

Which animal is the most likely food source for a lion?

crocodile

polar bear

zebra

Match the animal to its most common food source.

Column A

Column B

badger
grass
caterpillar
nuts
hare
fish
otter
insects and grubs
squirrel
leaves

The fox is an omnivore. This means it has more than one food source and will eat both plants and animals.

Sometimes foxes will eat small birds like blackbirds.

Blackbirds also eat a wide range of food sources. 

 

Look at the food chains below. Which food chains are correct?

strawberries blackbird fox

earthworms blackbird fox

field mouse big green arrow blackbird fox

Three different organisms exist in the same habitat. 

Which food chain correctly describes the feeding relationship between the organisms in this habitat?

spider raspberry bush ant

raspberry bush ant spider

Which animal is missing from the food chain?

  • Question 1

Here is a very simple food chain.

grass  sheep human 

 

This food chain shows us that grass is eaten by sheep – and then sheep are eaten by humans. Sheep mostly eat grass.

Which other animal from the list also obtains most of its food by eating grass?

CORRECT ANSWER
cow
EDDIE SAYS
Cows mainly eat grass. They take the nutrients from the grass and use it to make important materials for their own bodies.
  • Question 2

Humans eat sheep – we often call it lamb but you may have heard it being called mutton as well.

Which part of the sheep do we eat?

CORRECT ANSWER
meat
EDDIE SAYS
We eat the meat from sheep and other similar animals such as cows and pigs.
The meat from an animal such as a sheep is actually its muscle. The other parts of the sheep such as its horns and its wool are not suitable for humans to eat.
  • Question 3

Sheep only eat plants like grass. They do not eat meat.

Some humans also choose not to eat meat.

Complete this sentence.

People who only eat plants – and not meat – are known as _________________.

CORRECT ANSWER
vegetarians
EDDIE SAYS
Many people choose to be vegetarians. Some people believe it is wrong to kill animals for our food, others simply do not like the taste of meat.

A carnivore is an animal that only eats meat. A lion is a good example of a carnivore.
A herbivore is animal that only eats plants.
An omnivore is an animal that eats both meat and plants. Humans are good examples of omnivores who can choose to be vegetarians.
  • Question 4

Sometimes we can get more than one type of food product from an animal.

Think about cows.

Apart from meat, what other food products can we get from cows?

CORRECT ANSWER
milk
EDDIE SAYS
Most of the milk that we pour on our cornflakes and add to our cup of tea comes from cows. We can buy it from the supermarket or the local shop in big bottles.
Other animals such as goats and sheep also produce milk. We can even get milk from plants like the coconut and soya.
Milk is fantastically useful; we can use it to make cheese, chocolate, cream, yogurts, and of course milkshakes! Many of these foods are often called dairy products.
  • Question 5

Lions live on the African savanna.

Which animal is the most likely food source for a lion?

CORRECT ANSWER
zebra
EDDIE SAYS
The lion will hunt and eat the zebra. Polar bears and lions live in completely different habitats. The only time they might ever see each other would be in a zoo!
Lions and crocodiles are both predators and live in similar habitats. They occasionally fight each other but a lion does not hunt a crocodile for food.
  • Question 6

Match the animal to its most common food source.

CORRECT ANSWER

Column A

Column B

badger
insects and grubs
caterpillar
leaves
hare
grass
otter
fish
squirrel
nuts
EDDIE SAYS
All of these animals can be found in a woodland environment. The majority of the animals in this list do not eat each other, however there is one exception.
That's right, the badger will eat the caterpillar!
Can you draw up a food chain which links badgers, caterpillars and leaves?
  • Question 7

The fox is an omnivore. This means it has more than one food source and will eat both plants and animals.

Sometimes foxes will eat small birds like blackbirds.

Blackbirds also eat a wide range of food sources. 

 

Look at the food chains below. Which food chains are correct?

CORRECT ANSWER
strawberries blackbird fox
earthworms blackbird fox
EDDIE SAYS
Blackbirds do not eat field mice. The field mouse is much too big for a blackbird.
  • Question 8

Three different organisms exist in the same habitat. 

Which food chain correctly describes the feeding relationship between the organisms in this habitat?

CORRECT ANSWER
raspberry bush ant spider
EDDIE SAYS
In this habitat the raspberry bush is the producer. The fruits and leaves are eaten by ants who are then eaten by spiders.
Remember, in a food chain the arrow should always point in the direction of the organism that is feeding.
  • Question 9

Look at this food chain.

corn  chicken  _______

 

Which animal is missing from the food chain?

CORRECT ANSWER
human
EDDIE SAYS
The answer is of course a human. We eat tonnes of chicken.
Cows are herbivores and do not eat chickens despite being much bigger than them. Penguins live at the South Pole and eat fish. Chickens eat many things and have been known to eat earthworms, so it's safe to say that an earthworm definitely will not eat a chicken.
