Food webs
I can explain what is shown by a food web diagram and explain the effects that a change in the size of a population could have on other populations in the same community.

Lesson details
Key learning points
- A community of organisms is made up of interacting populations of species.
- A food web diagram represents several interconnected food chains within a community of organisms.
- A change in the size of a population will affect other populations in the food web.
Keywords
Habitat - A habitat is the place where an organism lives. It must provide food, shelter and a place to reproduce.
Population - A group of organisms of the same type in the same place is called a population.
Community - A community is made up of all the organisms that live in the same place.
Food chain - A food chain diagram shows how food is transferred from one population of organisms to another.
Food web - A food web diagram shows how all food chains interact with each other.
Common misconception
Changes in population within a food web will only impact organisms within the same food chain.
Exemplify that disappearance of one population could affect populations in all parts of the food web (CfU questions address this also).
