Food chains and food webs
These diagnostic questions and response activities (contained in the zip file) support students in being able to:
- Explain the order of organisms in a given food chain, using ideas about producers, consumers, predators and prey.
- Explain that the arrows in a food chain diagram represent transfers of biomass from producer to consumer, or from prey to predator.
- Recognise that the words and pictures in a food chain diagram represent populations of organisms in a community.
- Recognise that food web diagrams represent several interconnected food chains within a community of organisms.
- Use a food web diagram to predict and explain effects that a change in the size of a population could have on other populations in the same community.
The resources include details of common misconceptions and a summary of the research upon which the resources are based.
