Q
How are desert animals adapted to their environment? (4)
A
- Large surface area (to lose more body heat)
- Efficient with water
- Good in hot conditions
- Camouflague
2

7
Q
How can environmental change be measured by living indicators?
A
By studying organisms that are very sensitive to change:
- Air pollution can be monitored by lichen
- Water pollution can be monitored by invertebrate animals such as the mayfly
8
Q
How can environmental change be measured by non-living indicators?
A
- Satellites can measure the temperature of the sea and the amount of snow/ice cover
- Weather stations can tell us the temperature at various locations
- Rainfall can be measure with rain gauges
- Dissolved oxygen meters can measure how much oxygen is in water
