The features/characteristics an organism has in order to survive in its habitat.
1 of 16
Large Surface area compared to volume...
This means animals lose more body heat so they don't overheat. Desert animals have this.
2 of 16
Desert animals lose less water by...
producing small amounts of concentrated urine. They also sweat less. Camels do this by toolerating big changes in body temperature. Kangaroo rats live in burrows under ground because its cool there
3 of 16
Desert animals have a thin layer of body fat and a thin coat to...
help lose body heat. E.g. Camels keep all fat in humps
4 of 16
Camaflouge...
Desert animals have a sandy colour to help sneak up on prey and avoid predators.
5 of 16
Big ears...
help desert animals lose more heat
6 of 16
Arctic animals have adapted to...
lose less body heat. This is why they have small ears.
7 of 16
small surface area compared to volume...
live in cold conditions so have a round (compact) shape to keep surface area to a minimum to reduce heat loss
8 of 16
They are well-insulated...
Have a thick layer of blubber (fat under skin) for insulation. Also store energy when food is limited. Their thick fur coats keep them warm.
9 of 16
Camouflage...
white fur to hide from predators and sneak up to prey
10 of 16
Desert plants have adapted to...
having little water.
11 of 16
They have a small surface area compared to volume...
lose less water vapour from surface of leaves. Cacti have spines instead of leaves to reduce water loss.
12 of 16
Water storage tissues...
for example, Cacti store water in their thick stem.
13 of 16
Plants have maximising water absorption...
Some cacti have shallow but extensive roots to absorb water quickly over a large area. Others have deep roots to access underground water.
14 of 16
Some plants and Animals are adapted to scare (deter) predators...
Armour- roses have thorns. Cacti have spines. Tortoises have shells. Produce poisons- bees and poison ivy. Warning colours- Wasps
15 of 16
What are extremophiles...
Microrganisms that are adapted to live in seriously extreme conditions such as hot volcanic vents, in salty lakes or at high pressure on sea bed.
