- b1.4 Adaptations & inderpendence
- plants compete for
- food
- Absorb nutrients from soil
- space
- They need room for their leaves to spread out to obtain light for photosynthesis
- water
- Absorb water by their roots
- food
- animals compete for
- food

- water
- Need water in order to surviveed

- indicators
- invertebrates
- used as a marker of water pollution (heavy polluted water contains low levels of dissolved oxygen)
- oxygen sensor
- measures levels of oxygen
- rainfall gauge
- measures rainfall
- lichen
- shows levels of air pollution. is sensitive to sulfur dioxide
- rat-tailed maggots and sludge worms
- indicate high level of water pollution
- invertebrates
- adaptation is the process of change by which an organism or species becomes better suited to its environment.
- extremeophiles
- cryophile
- lives in extremely cold environments as has a cell membrane rich in lipids
- halophile
- lives in salty environments and can cope with the high concentrations of salt by expending energy to exclude salt from their cytoplsm
- acidophile
- lives in acidic environments where the pH level is less than 3
- thermophile
- lives in hot environments. has proteins that can withstand high temperatures
- an extremeophile is a microorganism that lives in conditions of extreme temperature
- cryophile
- plants compete for
