- Challenge pupils to suggest where there is competition between species in the food web. Reinforce their ideas by removing a plant species or adding two or more consumers and ask the pupils to predict the consequences.
- Extend the work by asking pupils to use food webs,
eg those generated in previous activities, to practise predicting the effects of altering the numbers of various organisms in a web. Use ICT simulations to test out the predictions made.

- predict the effects of altering the numbers of an organism in one part of a food web
