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.
Keywords
Food chain - A food chain shows how living things depend on each other for food.
Population - The population is the total number of something living in a particular area in a particular period of time.
Habitat - The place where a plant or animal lives is called its habitat.
Extinct - Animals or plants that have died out completely are extinct.
Endangered - An endangered plant or animal is one that is at risk of becoming 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.
Equipment
Pupils may wish to use age-appropriate secondary sources of information to find out more about changes in food chains, including endangered animals.
