Ecosystems, Biodiversity and Management
Rainforest goods and services, and the causes of deforestation
- 3 things to know
- Paper 1
Overview
Goods and services from rainforests including food, medicines, timber, recreation and carbon storage, how a hotter, drier climate threatens forest structure, fire risk, biodiversity and nutrient cycling, and how farming, resource extraction, population pressure and government policy drive deforestation.

What is the difference between a good and a service provided by an ecosystem?
Questions from this subtopic
Each one with the model answer underneath.
- 1
What is the difference between a good and a service provided by an ecosystem?
Model answer
A good is a physical product taken from it, such as timber; a service is a benefit it performs, such as storing carbon or regulating the flow of water.
- 2
Name foodstuffs that come from tropical rainforests.
Model answer
Brazil nuts, cocoa, coffee, bananas and wild fruits, together with fish and game taken from the forest and its rivers.
- 3
Why are rainforests so valuable as a source of medicines?
Model answer
A large share of prescription drugs began as tropical plant compounds, and most rainforest species have never been tested, so more treatments may still be found.
- 4
Which timbers are cut in tropical rainforests, and what are they used for?
Model answer
Tropical hardwoods such as mahogany and teak, sold for furniture, flooring and construction because they are strong, attractive and durable.
- 5
How do rainforests provide recreation?
Model answer
They attract ecotourists for wildlife watching, trekking and river trips, which brings income to local guides, lodges and national governments.
- 6
Which services do rainforests perform for the wider planet?
Model answer
They store enormous amounts of carbon, release water vapour that generates rainfall far beyond the forest, and hold soil in place against erosion.
