Aqa double science B1 Part 2: Animal Adaptations

These cards will show how different adaptations enable different animals to live within different habitats and extreme environments.

How desert animals are adapted to their environmen

Camels:

Camels have a large surface area compared to volume - this enables animals to lose more body heat to stop them from overheating in the sun.

Camels also have a thin coat of fur to help them sweat less and this also stops them from overheating by not storing to much heat in the fur.

Their long eyelashes stop sand getting into their eyes so can see more clearly.

Their humps store fat and water so they can go a long period of time without needing water.

Their sandy coloured fur is good use as camouflage so they could avoid predators or sneak up on prey.

How desert plants are adapted to their environment

Cacti:

Cacti have spines instead of leaves to reduce water loss.

Cacti also have a small surface area compared to their volume; this also reduces water loss.

They also store water in their thick stem.

Some cacti even have really extensive and shallow roots to help them absorb water more quickly. Others have really long roots to access water underground.

How arctic animals are adapted to their environmen

Polar Bears:

White fur - to avoid predators and sneak up on prey.

Thick furry coats - to keep them insulated in the cold weather.

Small surface area to volume - reduces heat loss.

Thick layer of blubber - insultion and acts as an energy store for when there is limited food.

Small ears - to avoid heat loss.

Strong legs - to help them swin in icy waters.

Brilliant sense of smell - to help them find prey.

Extremophiles.

Extremophiles are bacteria which are adapted to live in really EXTREME conditions such as:

- hot volcanic vents

- very salty lakes

- sea beds with high pressure
