Below are sample questions representative of the exercises included on this worksheet and related 6.88 Interpret Energy Pyramids skill assessments:

Problem 1Difficulty: Mastery

Students made an energy pyramid for a marsh but argued about what it means. Producers (cattails): 35,000 units Primary consumers (snails): 3,888 units Secondary consumers (duck): 388 units Tertiary consumers (fox): 38 units Which statement best corrects a common misunderstanding about energy pyramids?

Aif there are more herbivores than plants, energy at the herbivore level must be greater than at the plant level.

Bbecause decomposers break down dead matter, decomposers create new energy that makes the pyramid wider at the top.

Cenergy flows one way through trophic levels and is mostly lost as heat, so energy is not recycled back to producers like matter is.

Denergy is recycled in cycles, so the same energy moves from producers to predators and back again.

Solution & Explanation:Energy enters as sunlight (or chemicals) captured by producers. When organisms use energy for movement, growth, and keeping warm, much becomes heat and leaves the ecosystem. Matter cycles, but energy mostly flows one direction.

Problem 2Difficulty: Mastery

A research team estimated energy flow in an estuary. Producers (phytoplankton) store 100,000 kJ/m²/year. Transfer efficiencies were 6% (producers→primary consumers), 15% (primary→secondary), and 4% (secondary→tertiary). If the ecosystem must support at least 200 kJ/m²/year at the tertiary consumer level, what is the MINIMUM producer energy needed, assuming the same efficiencies?

AAbout 555,556 kJ/m²/year

BAbout 22,223 kJ/m²/year

Cabout 0 kJ/m²/year

Dabout 200,000 kJ/m²/year

Solution & Explanation:Work backward. Tertiary energy equals producer energy × (eff1×eff2×eff3). So producer energy ≈ 200 ÷ (0.06×0.15×0.04) ≈ 555,556 kJ/m²/year.

Problem 3Difficulty: Mastery

Students made an energy pyramid for a temperate forest but argued about what it means. Producers (oak leaves): 22,000 units Primary consumers (caterpillar): 2,444 units Secondary consumers (songbird): 244 units Tertiary consumers (owl): 24 units Which statement best corrects a common misunderstanding about energy pyramids?

Abecause decomposers break down dead matter, decomposers create new energy that makes the pyramid wider at the top.

Benergy is recycled in cycles, so the same energy moves from producers to predators and back again.

Cif there are more herbivores than plants, energy at the herbivore level must be greater than at the plant level.

Denergy flows one way through trophic levels and is mostly lost as heat, so energy is not recycled back to producers like matter is.
