(I)GCSE Topic 4.5 b) Food Webs

-Food Web allows us to provide a better description of the Ecosystem.
-Ecosystem is composed of the community of organisms which are interacting.
-Food Web allows us to show organisms feeding at different trophic levels.

  -Organisms can have multiple predators
  -Organisms feeding on multiple prey
  -This results in the foodchain becoming 'linked'.
