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

Teaching Table
Set out your lesson
Practise the bounded task in Food Webs & Interdependence; see exact limits before inferring broader coverage.
Understand eats/is eaten by and count linked relationships.
Exact directed source edges retained; earlier authorship is not learner attainment.
These supplied stage cards
Scrap paper and pencil; oral/pointing response where appropriate
Read readiness and decide on support without treating prerequisite authoring as learner readiness.
Open Show first and explain its model.
Use Guided Try with support and its separate adult key.
Close Show and guided keys before Try, unless this Try is explicitly supported.
Reflect on an actual attempt, including help used.
Use the supplied screen cards; copying the exact task to paper is optional, not required.
Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.
Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.
Use the complete materials on screen or print only the current sheet. Keep adult guidance out of learner view. Retain an earlier model only when the current step supplies it as context.
Teaching limits and safe use
These are finite task opportunities, not proof of mastery. Record what was attempted and what support was used.
A stipulated simplified web, not field population data or a deterministic prediction.
Use only invented scenarios and optional anonymous local notes. Do not request names, photos, family finances, medical data, accounts or uploads. Stop uncomfortable physical activity.

Check understanding
- Draws a food web from given data with arrows showing energy flow direction
- Predicts how the population of one species would change if another species increased or decreased
- Distinguishes a food web from a food chain and explains why webs are more realistic
- Identifies producers, primary consumers, secondary consumers, and apex predators
“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?”
