Food Webs & Interdependence
Construct and interpret food webs showing the interdependence of organisms in an ecosystem, explaining how a change in one population affects others
Typical age: 11–12 years
“If your child was shown a diagram with lots of animals connected by arrows, could they explain what it means — tracing what eats what — and predict what would happen if one animal disappeared from the web?”

Needs first
- Ecology VocabularyREQUIRED
Constructing food webs and understanding interdependence requires food web, producer, decomposer vocabulary
- Food Chains & Energy TransferREQUIRED
KS3 food webs and ecosystem interdependence extends KS2 introduction to food chains with producers, predators and prey
- Reading Food Web DiagramsREQUIRED
Constructing and interpreting food webs requires the food web diagram representation

- The Carbon Cycle
The carbon cycle involves organisms feeding, respiring, and decomposing — understanding food webs provides the biological context
- Energy Loss Between LevelsREQUIRED
Energy flow through trophic levels requires first understanding food webs and the feeding relationships they represent
- Species Distribution & Change
Understanding how species distribution changes affects food webs and ecosystem interdependence
- Pollination & Pollinator Decline
Pollinator importance is a specific case of ecosystem interdependence — the broader concept comes first
- Biodiversity & ResilienceREQUIRED
Biodiversity's role in ecosystem resilience is best understood in the context of food webs and interdependence
- Toxins Building Up in Food ChainsREQUIRED
Bioaccumulation occurs through food chains and webs — the feeding relationships must be understood first
