Science Quiz - Food Chains and Webs 01 (Questions)

Food chains and webs show how energy moves through living things. In KS3 Science, pupils learn how plants, animals, and predators are linked in ecosystems.

(quiz starts below)

Fascinating Fact:

Apex predators, like sharks and lions, sit at the top of food chains.

In KS3 Science, pupils study food chains and food webs to understand how energy is transferred between organisms. They also explore predator-prey relationships and how balance keeps ecosystems stable.

Key Terms

Producer: A plant or algae that makes its own food using sunlight.
Consumer: An animal that eats plants or other animals for energy.
Apex Predator: An animal at the top of a food chain with no natural predators.

Frequently Asked Questions (Click to see answers)

What is the difference between a food chain and a food web?

A food chain shows a single energy pathway, while a food web combines many food chains to show how organisms are linked in an ecosystem.

What happens if one part of a food chain is removed?

If one species is removed, it can affect the whole chain or web, leading to overpopulation or decline of other species in the ecosystem.

What are apex predators in KS3 Science?

Apex predators are animals at the top of food chains, such as lions or sharks, which have no natural predators in their habitats.

Science Quiz - Food Chains and Webs 01 (Answers)

1.

Plants are:

[ ]	decomposers
[ ]	herbivores
[ ]	primary consumers
[x]	producers

Plants produce their own food by photosynthesis

2.

Secondary consumers are usually:

[x]	carnivores
[ ]	decomposers
[ ]	herbivores
[ ]	producers

They can also be omnivores

3.

Omnivores eat:

[x]	animals and plants
[ ]	only animals
[ ]	only decomposers
[ ]	only plants

Herbivores eat plants. Carnivores eat animals (meat)

4.

Which of the following do you think is the odd one out in terms of their diet?

[ ]	Sheep
[x]	Lion
[ ]	Rabbit
[ ]	Elephant

The others are herbivores, in other words they are all primary consumers. A lion is a carnivore and is a secondary consumer (or higher, depending on what it has just eaten)

5.

Which of the following shows a correct food chain?

[ ]	Barn Owl → Dormouse → Barley
[ ]	Dormouse → Barley → Barn Owl
[ ]	Fox → Rabbit → Grass
[x]	Grass → Rabbit → Fox

A food chain always starts with an organism that can photosynthesise

6.

In the following food chain 'lettuce → rabbit → hawk', the rabbit is:

[x]	the primary consumer
[ ]	the producer
[ ]	the secondary consumer
[ ]	the top carnivore

A food chain ends at the top carnivore

7.

In the following food chain 'grass → grasshopper → rat → snake → hawk', the rat is:

[ ]	a herbivore
[ ]	the primary consumer
[x]	the secondary consumer
[ ]	the top carnivore

It eats grasshoppers which are the primary consumers of this food chain

8.

In the food chain 'grass → grasshopper → rat → snake → hawk', the hawk is .......

[ ]	the primary consumer
[ ]	the secondary consumer
[ ]	the tertiary consumer
[x]	the top carnivore

Nothing eats the hawk - hunting and catching it would take more energy than the predator would get from eating the hawk

9.

Rabbits and slugs eat lettuce. Hedgehogs eat slugs. Foxes eat rabbits. The rabbits get poisoned and many die. Which of the following is most likely to happen first?

[ ]	Foxes and hedgehogs will decrease in number
[ ]	Foxes and hedgehogs will increase in number
[ ]	Slugs and foxes will increase in number
[x]	Slugs will increase in number

The slugs do not have as much competition when the rabbits have died so there is more slug food. More food means that a larger population of slugs can be supported in the food chain

10.

Which of the following statements is NOT correct?

[ ]	Food chains always start with an organism that can produce its own food by photosynthesis
[x]	In a food web, arrows can point in any direction
[ ]	Primary consumers are herbivores
[ ]	Secondary consumers can be carnivores or omnivores

The arrows always show which way the energy is passing. In other words, they will always point towards the animal that is doing the eating and away from whatever is being eaten
