CAIE IGCSE Biology 19.2.3 Food web as a network
Practise interpreting food webs as linked food chains, including drawing networks and explaining effects when organisms are removed.
How this is tested
- construct a food web from feeding relationships, keeping all arrows in the correct direction
- explain how loss of a producer or predator can reduce food supply and alter linked populations
