Rainforest Food Webs

Science · Rainforests · conceptual

Understand how energy and nutrients flow through a rainforest food web — from plants (producers) to herbivores (primary consumers) to predators (secondary consumers) — and that decomposers like fungi and insects break down dead material on the forest floor, recycling nutrients back into the soil for plants to use again

What mastery looks like

  • Construct a simple rainforest food chain with at least three levels: producer → herbivore → predator
  • Explain the role of decomposers in breaking down dead material and returning nutrients to the soil
  • Use the terms producer, consumer, and decomposer correctly

Check your understanding

Can Rainforest Food Webs explain a rainforest food chain — like how a fruit tree feeds a monkey, the monkey might be hunted by a jaguar, and when things die, tiny organisms break them down to feed the trees again?
