- Features that enable organisms to survive
- Cold
- Hot
- Rainforest
- Wide spread of roots to collect rain and dew from the surface
- Deep tap root to reach deep underground water
- Small SA reduces water loss
- Thin fur for maximum heat loss
- Specialized kidneys make concentrated urine
- Large SA maximums heatloss
- Animal behavior e.g basking and burrowing
- Hot
- Extreme Environments
- HOT- Special proteins that aren't damaged by high temps
- DEEP SNOW- Flagella help microbes to swim up to the surface
- BRIGHT LIGHT- Red pigments protect microbe- Absorbs radiating heat to warm
- NO LIGHT- Use chemicals to make food
- SALTY- Microbes themselves contain high levels of salt
- Bio-indicators
- Lichens don't grow in SO2
- Aquatic invertebrates Mayfly live in clean waterBlood worms in polluted water
- Plants
- Intraspecific- members of the same species competiting
