Below are sample questions representative of the exercises included on this worksheet and related 7.31 Food Chains, Food Webs, and Energy Pyramids skill assessments:

Problem 1Difficulty: Mastery
Use the image showing four student models of the same grassland ecosystem. Which model correctly represents both feeding relationships and decreasing available energy at higher trophic levels?
AModel 3
BModel 2
CModel 4
DModel 1
Solution & Explanation:Model 1 is the only model that shows the correct feeding order and lower energy values at higher trophic levels.
Problem 2Difficulty: Mastery
A fox can be supported by two berry-based paths: berries -> mouse -> fox and berries -> insect -> frog -> fox. Which conclusion is best?
ANeither path can deliver energy to a fox.
BBoth paths deliver the same energy because they begin with berries.
CThe frog path can deliver more fox-level energy because it has more organisms.
DThe mouse path can deliver more fox-level energy because it has one less transfer step.
Solution & Explanation:A shorter path loses energy fewer times, so the mouse path can deliver more energy to the fox.
Problem 3Difficulty: Mastery
Student A says top predators always have the most energy because they are strongest. Student B says arrows point toward the organism that receives the energy. Student C says decomposers create new energy. Which student is correct?
AStudent A
BStudent B
CStudent C
DStudents B and C
Solution & Explanation:Student B is correct because food-web arrows point to the organism that gets the energy.
