Below are sample questions representative of the exercises included on this worksheet and related 6.81 Food Chains, Food Webs, and Energy Flow skill assessments:

Problem 1Difficulty: Mastery
Use the coastal food web. Which revision would make the model scientifically stronger?
AAdd decomposers and be sure all arrows point from food to eater.
BReverse all arrows toward producers.
CRemove the seagrass from the model.
DPut the shark at the bottom because it is largest.
Solution & Explanation:A stronger model should include decomposers and correct arrow direction so it shows energy flow accurately.
Problem 2Difficulty: Mastery
Which statement about human impact on food webs is best supported across many ecosystems?
AReducing producers can affect many other organisms because producers bring most energy into the web.
BHuman actions only affect top predators.
CFood webs are not changed by habitat loss.
DDecomposers prevent all ecosystem damage.
Solution & Explanation:Producers form the energy base of most food webs, so damaging them can affect many connected populations.
Problem 3Difficulty: Mastery
Which model best represents a strong food web for this standard?
AA diagram with producers, several consumers, decomposers, and arrows showing energy moving from food to eater
BA list of animal names with no arrows
CA chain that starts with a hawk and ends with sunlight
DA diagram with only predators and no producers
Solution & Explanation:A strong model for this standard shows multiple feeding relationships, the direction of energy flow, and the role of decomposers.
