Cold Environments
Cold environment biodiversity
- 3 things to know
- Paper 1 section B
Overview
Why so few species live in the cold and why that makes the ecosystem fragile, and the threats from warming, thawing permafrost, oil spills, roads, over-fishing, pollution and hunting.

Key term
How does a warming climate threaten the species of a cold environment?
Questions from this subtopic
Each one with the model answer underneath.
- 1
Why is biodiversity in a cold environment so low compared with a rainforest?
Model answer
A long freezing winter, a very short growing season and thin, poor soils mean only a few highly specialised species can survive there.
- 2
Why does having so few species make a cold ecosystem fragile?
Model answer
Food chains are short with few alternatives, so if one species declines the animals that feed on it have almost nothing else to turn to.
- 3
Why does damage to tundra vegetation last for decades?
Model answer
Plants grow extremely slowly in the cold and in so short a summer, so vehicle tracks and cleared ground stay bare for many years.
- 4
How does a warming climate threaten the species of a cold environment?
Model answer
Shrubs and trees spread polewards and out-compete the mosses, lichens and low plants, while animals that depend on snow and ice lose the habitat they need.
- 5
How does thawing permafrost damage cold environment habitats?
Model answer
The ground slumps, collapses and floods, breaking up the plant cover and changing the drainage, so the species living there are displaced.
- 6
Why is an oil spill in a cold environment particularly damaging?
Model answer
The cold slows the natural breakdown of oil, so it stays in the soil, ice and water for decades and keeps poisoning wildlife.
