What animals are there at the Poles?
The harsh climate at the North and South Poles may not seem encouraging to life.
The animals live in there have adapted to the extreme cold with fur and the layers of fat. The camouflage coloring of white bears, seals, whales, reindeer, walruses, the white musk ox, wolves , the husky dog, and the various rodents is also giving a coverage to live in the Poles.
There are also number of sea birds who do the migrations each year, and during the short Arctic summer, there are mosquitoes.
In the South Pole the sea life is far richer than at the North Pole. The sea-life has become richer with the migratory birds, penguins, different types of seal and whales.
The plants at the Poles
Although there are no lush plat-life in Arctic, approximately 1700 species of plants live in the Arctic including are mosses, lichens ,heathers and various weeds. South at the Arctic, because life on the ground is reduced there is little vegetation; Antarctic hair grass and Antarctic pearlwort, with hardly any moss or lichens.
The plants have adapted to the climate in various ways. The size of the plants become smaller with the shallow roots system. The shallow roots compensate for the thin layer of soil while the small leaves minimize the water amount lost through the surface of the soil. Many plant species in the Poles can grow under a layer of snow as well.
What about the human?
And of course, in the Arctic there live the eskimos, in the Antarctic, since it is an ideal place for research there are people; scientists.
What plants are there in the desert?
Deserts are the regions which have very low rainfall. Which means the life of a plant lasts only a short while.
Not only sand, but also there are stony ground and rocky formations.
The temperature is remarkable. In the day it is 50oC and it is going to minus 10oC at night. So, with this harsh condition, the animals and the plants who live there have had to adapt.
For an example, in the Sahara Desert, plants are having a very rapid cycle. They do their flowering and the reproduction during the rare but the short rainy season and the seeds surviving in the soil until the next rain. The plants have long roots in search of warmth, reduced leaves, and bodies with reserves of water.
In the desert, wherever there is a reserve of water, an oasis springs up. It was not nature who made them , but men who dug holes and irrigated the water, planted date palms and tamarind trees, as well as tomato plants, onions, melons, courgettes and peppers.
The animals in the dessert
The animals which have adapted best are the reptiles and insects. Other than that, the animals had to overcome various challenges including lack of water to thrive in the desert and the excessive heat.
The sand cats; being the only cat species living in the desert, the genus oryx, grant’s gazelle and there are also various rodents, dromedaries and camels, gazelles, goats, antelopes, wolves and numerous birds including desert larks, sandgrouse
