Adaptations Flashcards
How do organisms survive in many different environments?
Because they are adapted to them
What are desert animals adapted to?
To save water
Keep cool
How are desert animals adapted?
Large surface area compared to volume
Efficient with water
Good in hot conditions
Camouflage
How is large surface area compared to volume important for desert animals?
Lets desert animals lose more body heat
Stops them overheating
How is efficiency with water important for desert animals?
Lose less water by producing small amounts of concentrated urine
Little sweat
Why is it important for desert animals to be good in hot conditions?
Have thin layers of body fat
Have a thin coat to help them lose heat
Why is camouflage important for desert animals?
A sandy colour gives good camouflage to avoid predators
Sneak up on prey
How have Arctic animals adapted?
To reduce heat loss
How are Arctic animals adapted?
Small surface area compared to volume
Well insulated
Camouflage
Why is having a small surface area compared to volume important for Arctic animals?
To reduce heat loss
Why is it important for Arctic animals to be well insulated?
Thick layer of blubber for insulation or an energy store
Thick coats keep body heat in
Why is camouflage important for Arctic animals?
Avoid predators
Sneak up on prey
What have desert plants adapted to?
Having little water
How are desert plants adapted?
Small surface area compared to volume
Water storage tissues
Maximising water absorption
Why is it important for desert plants to have a small surface area compared to volume?
Plants lose water from the surface of their leaves
To reduce water loss
Small surface area to reduce water loss
