B7: Quiz 5 – Answers
1)
a) Extremophiles
b) High temperature and high pressure
c) Any two from geothermal pools, very salty lakes, polar regions, deep ocean beds and the tops of mountains
2) Structural, behavioural and functional
3)
a)
i) To conserve water
ii) Functional
4) Any 2 from:
5)
a) Functional
b) By hibernating, the animals are lowering their metabolism, which conserves energy. Also, hibernating means that these animals do not have to find food in winter when food is scarcer.
6)
a) Structural
b)
7) Any 2 from thick fur, lots of fat/ a layer of fat, a small surface area to volume ratio and white fur
a) Extremophiles
b) High temperature and high pressure
c) Any two from geothermal pools, very salty lakes, polar regions, deep ocean beds and the tops of mountains
2) Structural, behavioural and functional
3)
a)
- The large feet allows camels to walk on sand/ means that they do not sink
- They are sand coloured to blend in with the desert (camouflaged), which prevents predators from seeing them
- They have a large surface area to volume ratio so that they do not overheat.
i) To conserve water
ii) Functional
4) Any 2 from:
- Migrating to warmer climates in winter
- Hunting in packs
- Sitting in the sun or shade to either heat up or cool down
- Mating rituals like putting on a show (peacock feathers) or fighting off others (stags fighting each other)
5)
a) Functional
b) By hibernating, the animals are lowering their metabolism, which conserves energy. Also, hibernating means that these animals do not have to find food in winter when food is scarcer.
6)
a) Structural
b)
- Cacti have swollen stems to store lots of water
- The spines reduce the amount of water loss/ transpiration
7) Any 2 from thick fur, lots of fat/ a layer of fat, a small surface area to volume ratio and white fur
Questions
1)
a) What is the name that we give to organisms that live in extreme environments?

c) An example of a location of an extreme environment is a hot volcano. Give 2 other locations.
2) Without looking at the later questions, what are the three different categories for adaptation?
3) The image below is of a camel that lives in the desert.

3) The image below is of a camel that lives in the desert.
a) Explain how the structural adaptations on the labelled diagram above help the camel to live in the hot desert.
b) Camels produce urine that is very concentrated.
i) Why do they do this?
ii) Which of the three adaption categories does this adaptation fit into?
4) Give 2 different examples of behavioural adaptations. You do not need to explain the behavioural adaptations.
5) Some animals hibernate during winter.
a) Which of the three adaptation categories does hibernating fit into?
b) Why do animals hibernate?

6) The picture below shows some of the adaptations for cacti.
a) Which of the three adaptation categories do both of the adaptations above fit in to?
b) Explain why both of the adaptations for the cacti give it a greater chance of survival in the desert.
7) The picture below is of an artic fox.
b) Explain why both of the adaptations for the cacti give it a greater chance of survival in the desert.
7) The picture below is of an artic fox.
Give 2 structural adaptations for an artic fox. You do not need to explain why they have these structural adaptation.
