Lesson details
Key learning points
- The name or picture of each living thing in a food chain represents the whole population of that plant or animal.
- A change to one living thing can affect other living things in the same food chain.
- An increase or decrease in the population of a plant or animal can have an effect on the food chain.
- Changes in food chains may lead to animals and plants becoming endangered or even extinct.
Common misconception
Pupils often think that the words and pictures in a food chain represent an individual plant or animal rather than populations of living things within a habitat.
It is made explicit within the examples in this lesson that each living thing named in a food chain represents a population of that type, or species, of plant or animal within a habitat.
