Lesson details
Key learning points
- Predators are hunters and prey are hunted.
- Different factors can affect the population sizes of predators and prey (e.g. disease).
- There is a relationship between the predator and prey population sizes, each is impacted by changes in the other.
Keywords
Predator - An animal that hunts and eats another animal.
Prey - An animal that is caught and eaten by another animal.
Population - A group of organisms of the same type, in the same place, is called a population.
Common misconception
The change in the size of a population will only affect another population if they are predator-prey
Ensure that pupils are given opportunities to see how changes in population size impact all other organisms in the food chain.
