Science Quiz - Food Webs (Answers)
Explore the wonders of KS2 Science with this quiz on food webs – the amazing cycles of who eats whom!
Food webs, or chains, reveal how living things transfer energy by eating. All plants and animals need energy to live. Plants, like grass, make energy from sunlight. Herbivores, such as rabbits, eat plants, passing on the energy. Predators, like foxes, eat herbivores, continuing the energy flow. These cycles are food chains.
What food do different organisms need? Where do they find it? What supports all life on Earth? Learn about producers and consumers in this fun quiz on food chains and food webs!

Plants use photosynthesis to convert sunlight into food
|
Because plants create their own food from sunlight, using photosynthesis, they are the only means of transferring energy from the Sun to all life on Earth

Herbivores are called primary consumers because they are able to gain all their energy through digesting plants
|
Humans are omnivores
|

Plants always come at the beginning of a food chain, which is why they are known as producers - only plants can turn sunlight into food
|
Arrows show the way in which energy is moving

Producers are always green plants
|
Decomposers include earthworms, woodlice, fungi and bacteria, and represent the end of any food web because they feed on dead organisms

Caterpillars, rabbits and cows are all herbivores and so primary consumers
|
The rose is the producer, the aphid is the primary consumer and the ladybird is the secondary consumer
