Biomes
Biomes are large regions with typical climate and life.
About this topic
Biomes are large regions defined by climate and typical vegetation. Examples: tropical rainforest (hot, wet, extremely diverse), savanna (grassland with scattered trees), desert (dry), temperate forest (four seasons), taiga (cold coniferous forest), tundra (frozen, low plants), grassland and aquatic biomes.
Temperature and rainfall are the main factors deciding the biome, which is why biomes follow latitude and altitude. Moving from the equator to the poles, you pass from rainforest to savanna, desert or temperate forest, then taiga and tundra. Climbing a tall mountain shows a similar sequence in miniature.
Organisms in each biome have adaptations. Cacti store water and have spines instead of leaves, camels tolerate heat and dehydration, polar bears have thick fur and blubber, and rainforest trees grow tall to reach light and have drip-tip leaves to shed heavy rain. Rainforests hold over half of land species despite covering a small area.
Biome maps help scientists predict how climate change will move vegetation zones and where to focus conservation. Do not confuse a biome with an ecosystem: a biome is a huge region type, whereas an ecosystem can be as small as a pond. Soil, not just climate, also matters.

Quick check
Use cases: where Biomes helps
- Homework: review the key idea behind Biomes before you start a problem set.
- Exam revision: use the quick check to test whether you can recall Biomes without notes.
- Visual learning: play with the interactive lab to see how Biomes changes when you adjust its inputs.
- Teaching a friend: explain Biomes in your own words, then compare your version with the key ideas.
Biology underpins medicine, farming, conservation and biotechnology.
