Commonly confused
Pairs that lose marks when they are blurred together.
Producer vs Consumer
Producer: a green plant that makes its own food by photosynthesis. Consumer: an animal that gets its energy by eating other organisms.
Primary consumer vs Secondary consumer
Primary consumer: an animal that eats plants. Secondary consumer: an animal that eats plant-eaters.
Food chain vs Food web
Food chain: a single line along which energy passes from one organism to the next. Food web: the many feeding links that join species together.
Questions from this topic
Each one with the model answer underneath.
- 1
What is an ecosystem?
Model answer
A community of plants and animals that interact with each other and with the non-living parts of the place they live in.
- 2
What is a producer, and how does it obtain the energy it needs?
Model answer
A green plant that makes its own food by photosynthesis using sunlight, so it forms the first link of any feeding sequence.
- 3
What is a consumer, and what is the difference between a primary and a secondary consumer?
Model answer
An animal that gets its energy by eating other organisms; a primary consumer eats plants, while a secondary consumer eats primary consumers.
- 4
What is a decomposer, and what does it do to dead material?
Model answer
A bacterium or fungus that breaks down dead plant and animal remains, releasing the nutrients they hold back into the soil.
- 5
What does a food chain show?
Model answer
The single line along which energy is passed from one organism to the next as each is eaten by the one above it.
- 6
Why does a food web give a more realistic picture of feeding than a single food chain?
Model answer
Because most animals eat several different things, so a web shows the many feeding links that join species together rather than just one line.
