Nutrient Cycling in Thin Soil
Understand the paradox of nutrient cycling in rainforests — despite lush growth, rainforest soil is typically thin and nutrient-poor because most nutrients are locked in living organisms, not the soil; decomposition is rapid in the warm, wet conditions, and nutrients released from dead material are immediately absorbed by plant roots and fungi, creating a fast, closed-loop recycling system

“Can your child explain the surprising fact that rainforest soil is actually poor and thin — that the nutrients aren't in the ground but locked inside the living plants and animals, constantly being recycled?”
