Adaptations

Some animals are adapted to living in very cold conditions. How do they keep warm?

Which type of adaptations do some have to help reduce heat loss?

Give two examples of anatomical adaptations that help to decreases heat loss.

How does having excellent insulation cut down heat loss? (Use the example of an Arctic fox.)

How does being quite large, with small ears help to decrease heat loss?

Animals may try to avoid the cold by changing their behaviour. Give two examples of what they may do.

What do penguins have to help reduce heat loss?

How does this work?

Other organisms that live in cold climates may have which type of adaptations?

Give an example of one of these adaptations.

Give two examples of an animal and a plant which live in deserts.

To increase heat loss, animals adapt in a variety of ways. Give an example of one anatomical adaptation that a camel has to increase the loss of heat.

Give another example of an anatomical adaptation that animals which live in hot areas usually have.

How do these factors help animals to lose more heat?

Give two examples of how other behavioural adaptations help animals to lose more heat.

Give an example of how to reduce heat gain animals may change their behaviour.

Why can cacti reduce water loss?

What are organisms that can survive in hot conditions called?

Why can some bacteria live in hot springs?
