- Adaptions to Abiotic Factors
- Temperature
- Low temperatures freeze cells
- Birds and mammals respire to generate heat
- High temperatures denature proteins
- Some bacteria survive at over 110 degrees
- Enzymes function within a temperature range
- Fluctuating temperatures cause problems
- Lizards sunbathe and hibernate
- Low temperatures freeze cells
- Light
- Plants have evolves certain pigments to absorb light
- Woodland floor plans have evolved red and blue pigments to make the most of light
- Plants have evolves certain pigments to absorb light
- pH
- Enzyme damage to low or high pHs occurs in organisms with exposed tissues/roots
- Cowslip live in alkaline chalk soils
- Lichens cannot surive acidic conditions
- Enzyme damage to low or high pHs occurs in organisms with exposed tissues/roots
- Water
- Specific requirements for breeding or those who lose water
- Turbulence/ Physical Damage
- Some species well adapted to survive turbulent conditions
- Brown seaweed coated with mucus and flexible
- Some species well adapted to survive turbulent conditions
- Temperature
