Science B1b organisms in their environment
Polar bear
Polar bears are well adapted for survival in the Arctic. They have:
a white appearance as camouflage from prey on the snow and ice
thick layers of fat and fur for insulation against the cold
a small surface area to volume ratio, to minimise heat loss
a greasy coat that sheds water after swimming
large furry feet to distribute their load and increase grip on the ice
Snowshoe hare
In winter its fur is white and in summer it is reddish brown. So it has all year round
camouflaging against predators.
Artic plants
Artic plants often grow very close to the ground with small leaves. This helps them
conserve water and avoid damage from the bitter artic winds.

These plants can store water in their stems. They have widespread root systems that can
collect water from a large area. With spines instead of leaves they minimise the surface
area and so reduce water loss by transpiration, they also contain poisons, and their
colours warn off herbivores and predators.
Other adaptations
Animals and plants may have specific features that adapt them to their environment.…read more

Science B1b organisms in their environment
Every organism has certain features or characteristics that allow it to live successfully in its
habitat. These features are called adaptations, and we say that the organism is adapted to its
habitat. Organisms living in different habitats need different adaptations.…read more
