1
Label the adaptations of the polar bear and
explain how they help with survival
What do the following compete for? Animals Plants

Label the adaptations of the fennec (desert fox)
and explain how they help with survival
1.4 Interdependence And Adaptation

• How can human activity affect the distribution of
  organisms?

Name three adaptations of prey that deter
predators.
Explain how climate change may lead to a
short-haired arctic fox being more likely to
survive than a long haired one.
Bacteria can be adapted to survive in extreme
conditions. Explain how
Name the three pieces of equipment and state what
they measure
How is the cactus adapted to survive in the
desert?
How can the following living organisms be used as
pollution indicators? Lichens Aquatic
invertebrates
What is a pollution indicator? .
What is an extremophile?
How are desert animals adapted to cope with very
cold nights?
Many factors can cause environmental change. Give
an example of A living factor A non-living
factor

• Label the adaptations of the polar bear and
  explain how they help with survival
• Small surface area to volume ratio minimizes
  heat loss
• Small ears / nose
• Thick fur insulation
• Thick layer of body fat insulation
• Waterproof fur reduce heat loss from
  evaporation when wet
• White - camouflage

What do the following compete for? Animals food,
mates, territory Plants light, space, water and
nutrients from soil

• Label the adaptations of the fennec (desert fox)
  and explain how they help with survival
• large surface area to volume ratio increases
  heat loss
• Large ears - more heat loss
• thin fur increase heat loss
• Sandy colour - camouflage

1.4 Interdependence And Adaptation

• How can human activity affect the distribution of
  organisms?
• Destroy an animals food source or habitat
  building, chemicals, farming
• Introduction of new competing species
• Global warming

Name three adaptations of prey that deter
predators. Thorns / poisons / warning colours
Explain how climate change may lead to a
short-haired arctic fox being more likely to
survive than a long hairde one. Temperature is
increasing Short haired fox able to lose heat
better so less likely to overheat Short haired
fox more likely to survive and pass genes on
Bacteria can be adapted to survive in extreme
conditions. Explain how Tolerate High salt
concentration High temperature
High pressure
Name the three pieces of equipment and state what
they measure maximum-minimum thermometer
temperature Rainfall gauge rainfall in set time
period

• How is the cactus adapted to survive in the
  desert?
• roots widespread collect water from a large area
• Roots deep collect water because surface likely
  to dry out quickly
• No leaves reduce surface area from which water
  can be lost
• Stem able to swell store water

How can the following living organisms be used as
pollution indicators? Lichens Monitor air
pollution higher population better quality air
(less SO2) Aquatic invertebrates monitor water
pollution concentration of dissolved oxygen
ceratin species can tolerate very low O2
What is a pollution indicator? Living organism
that shows the level of pollution in an area
through changes in its distribution or
abundance.
What is an extremophile? A microorganism that is
adapted to live in extreme conditions.
How are desert animals adapted to cope with very
cold nights? Burrows - insulation
Many factors can cause environmental change. Give
an example of A living factor New competitor eg
grey squirrel A non-living factor Change in
temperature or rainfall
