How does a polar bear adapt to its surroundings?

1. White appearance so that it can sneak up on its prey.
2.Thick layers of fat and fur for insulation.
3.A small surface area to volume ratio for minimum heat loss
4.A greasy coat to shed water after swimming.
5.Large furry feet to distribute their load across the surface.

How does a camel adapt to its surroundings?

1.Large, flat feet to spread their weight on the sand.
2.Thick fur on the top of the body for shade, thin elsewhere.
3.Large surface area to volume ratio for maximum heat loss.
4.Lack of water tolerance, lose little water through urination and perspiration.
5.Ability to tolerate high temperatures.
6.Long rows of eyelashes to keep out the sand.

10

How does a cactus adapt to its surroundings?

1.Stems that store water
2.Widespread root system to collect water.
3.Spines instead of leaves to minimize water loss by transpiration.
4.Spines to protect from predators.

11

What are extremophiles?

Organisms that live in very extreme environments. Conditions include:
1.High temperatures
2.High concentrations of salt in water
3.High pressures

Pollution indicators:

Bushy lichens: Need really clean air.
Leafy lichens: Can survive a small amount of pollution.
Crusty lichens: Can survive in more polluted air.
Mayfly larva: Clean water
Freshwater shrimp: Low water pollution.
Water louse: High pollution
Rat-tailed maggot- Very high pollution.

Rainfall and temperature:

Measured with a rain gauge, temperature measured with a thermometer.
