SHIP OF THE DESERT BY SITHARA.M.N
There are Different regions on the earth
Desert Grass land Fresh water regions Polar regions Marine regions
Animals and plants Most plants and animals are specially adapted to survive in a particular region. Most plants and animals are specially adapted to survive in a particular region. They have developed special features to suit the demands of their environment. They have developed special features to suit the demands of their environment. This is called adaption. This is called adaption.
Some examples of adaption
All birds have similar characteristics. But many water birds have features that are different from those birds live on land. Long legs are good for wading These wings act as flippers Webbed feet for swimming
Some animals are camouflaged to blend in with their surroundings. Some animals are camouflaged to blend in with their surroundings. This keeps them safe as it is more difficult for other animals to see them or catch them for food. This keeps them safe as it is more difficult for other animals to see them or catch them for food. This lizards skin is so similar to the rock colour. These zebra could easily be mistaken for bushes from a distance. This lion blends in well with the grassy background.
These animals have adapted to live in the hot climate of the desert. Camels store water in their humps. Ostriches have long eyelashes to keep out the sand. Snakes glide across the hot sands and can shed their skin
These animals have adapted to be more suited to cold temperatures. Layers of fat keep the seals body warm, and small ears stop heat loss. Polar bears are kept warm by their body fat. Deer have a warm layer of fur.
Want to know more about some of them you are familiar with....?
Camels How do camels adapt to their environment? Camels have many adaptations that allow them to live successfully in desert conditions.
. Deserts are hot and dry. Winds blow sand all around, So a camel has long eyelashes.
Why do camels have long eyelashes?
The long eyelashes keep sand out of the camel's eyes. Thick eyebrows shield the eyes from the desert sun.
Camel have nostrils which can close A camels nostrils can close so it doesn't get sand up its nose.
Other Adaptations: A camel can go a week or more without water, and they can last for several months without food. They can drink up to 46 litres of water at one drinking session! Camels store fat in the hump, The fat can be metabolised for energy.
Camels feet are wide and padded so they can walk on sand more easily. Their huge feet help them to walk on sand without sinking into it.
Camels have thick lips so they can eat the prickly desert plants with out feeling pain.
A polar bear lives in the cold, snowy Arctic lands. Why are polar bears white? Their white fur helps them blend in with the snow and ice. How does a polar bear keep warm? A polar bear has a layer of fat under its skin which helps it stay warm. It also has a thick layer of fur.
Giraffe Their long necks allow them to feed among treetops and spot predators.
Penguins Penguins live on pack ice and in the oceans around Antarctica. The dark coloured feathers of a penguin's back surface absorb heat from the sun, so helping them to warm up too.
Penguins have webbed feet for powerful swimming. Their bodies are streamlined to reduce drag in water. Their wings, shaped like flippers, also help them "fly" underwater at speeds up to 15 mph.
