Food Webs

A food web is a diagram that shows how food chains are linked together into more complex feeding relationships

A food web is more representative of actual feeding pathways within an ecosystem because:

  • Organisms can have more than one food source
  • Organisms can have more than one predator

This means that, unlike a food chain, organisms in a food web can occupy more than one trophic level

  • Hint: When constructing food webs, position organisms at their highest trophic level (keeps all arrows pointing in same direction)
