I keep getting “Energy flow” questions wrong in Ecosystem & Ecology. What's the trap?

thinking energy is recycled like nutrients.

The usual trap: thinking energy is recycled like nutrients. How to avoid it: nutrients cycle, but energy flows one way and dissipates as heat. Go back to the definition — energy moves one-way through an ecosystem — from the sun to producers to consumers — and is lost as heat at each step.
