Tropical Rainforests
Rainforest biodiversity
- 3 things to know
- Paper 1
Overview
Why rainforests hold the greatest biodiversity on land, layered niches and endemic species, their value to medicine, and the threats from specialisation, habitat fragmentation, hunting, the wildlife trade and extinction.

Questions from this subtopic
Each one with the model answer underneath.
- 1
What does biodiversity mean?
Model answer
The range of different plant and animal species living within an ecosystem.
- 2
Why do rainforests hold greater biodiversity than any other land ecosystem?
Model answer
The hot, wet conditions allow growth all year round, and the forests have existed undisturbed for a very long time, so a huge number of species has had time to evolve there.
- 3
How does the layered structure of the forest raise the number of species it supports?
Model answer
Each layer has its own light, humidity and food conditions, creating many separate niches that different species can specialise in.
- 4
What does it mean to say a species is endemic to one rainforest?
Model answer
It lives naturally there and nowhere else on Earth, so if that forest is destroyed the species is lost completely.
- 5
Why does the loss of rainforest species matter to medicine?
Model answer
A great many drugs already in use were first found in rainforest plants, and most species have never been tested, so possible future cures are being destroyed before anyone has studied them.
- 6
Why do highly specialised species suffer most when a rainforest is disturbed?
Model answer
They depend on a very narrow set of conditions or a single food source, so they cannot adjust or move elsewhere when those conditions change.
