- BIOME's
- Tropical rainforest - BIGGEST BIOME
- Covers around 7% of the earth's suface (S. AMERICA and BRAZIL), used to cover 14%.
- Rainfall can reach up to 400 inches per year.
- Epiphytes - such as orchids, grow on surfaces of trees.
- More than 20% of the world's oxygen is produced in the AMAZON rainforest.
- One of the largest organic stores of CARBON - AMAZON sequesters 17% of all terrestrial carbon.
- 1% of 16,000 tree species on earth store around 50% of the biome's carbon.
- One of the largest organic stores of CARBON - AMAZON sequesters 17% of all terrestrial carbon.
- Stores around 650 billion tonnes of carbon - when burned, lots of CO2 released
- Tundra - SMALLEST BIOME
- ARCTIC - northern hemisphere
- Impossible tree growth due to frozen soil. MOSS and LICHEN's grow.
- During summer, top layer melts, leaving soggy marshes, lakes, bogs and streams.
- Reaches temperatures of -28 to -50*C.
- ALPINE
- Soils at high altitude means tree growth is not possible.
- Does not have permafrost like the arctic and is better drained.
- mountain goats, sheep, grasshoppers, dwarf shrub.
- -12 to 10*C annual temperatures, and 12 inches of rainfall.
- ANTARCTIC
- LICHENS, MOSS and ALGAE.
- no precipitation, but averages at -49*C.
- Penguins, seals, crustaceans (crabs), fish (cod).
- Human activity affects tundra by reducing the ozone layer and allowing UV and heat to enter the biome.
- Has 6-10 inches of precipitation a year.
- Small amount of C is stored in plants and taken in by them (Shrubs and grass)
- ARCTIC - northern hemisphere
- Tropical rainforest - BIGGEST BIOME
