Common mistakes

Misconceptions students bring to ecosystems

Specific errors to watch for when reviewing student work — pulled from classroom research and teacher reports.

1. 1

   Thinking energy cycles through ecosystems like matter does.

   What to teach instead: Energy flows one way (sun → producers → consumers); only matter cycles.

2. 2

   Believing decomposers are not part of food webs.

   What to teach instead: Decomposers are essential — they recycle nutrients back to producers.

3. 3

   Confusing predator-prey balance with extinction.

   What to teach instead: Population sizes oscillate naturally; declines are only extinctions when reproduction can't recover.
