- Extreme Environments
- Some organisms have adapted to living in the deep sea
- Deep under the sea conditions are hard to live in - there is virtually no light which means that plants can't grow because they can't photosynthesise. Food is scarce as there are no plants and animals survive on scrap that sink from the shore.
- Deep sea fish are able to emit light from parts of their body.
- e.g. The angler fish has a rob shaped spine which gives out light. The light attracts prey which the fish then eats.
- Deep sea fish often have huge mouths which makes it easier for them to catch particles of food.
- Many deep sea fish have huge eyes adapted to the dark and long feelers which helps them locate prey.
- Organisms in polar regions have adapted to the cold
- e.g. Polar bears - thick layers of blubber for insulation and as an energy source when food is scarce.
- White fur used for camouflage. Big feet - spreads their weight evenly - stops them sinking into snow or breaking thin ice.
- e.g. Penguins huddle together to conserve heat. Thick layer of blubber and oily feathers which shed water.- reduce heat loss.

- Organisms in volcanic vents are adapted to high temperatures
- Bacteria is adapted to the high temperature and pressure near the vents.
- Chemicals from the vents support bacteria that use chemosynthesis to make their own food.
- Animals feed on the bacteria.
