Deserts

Deserts are associated with  very dry climates, high temperatures, high winds and lots of sand with little landscaping except from sand peaks and no civilization for miles on end, this however isn't what differentiates desert biomes. Desert biomes are actually inhospitable living habitats which only flora and fauna who have evolved to live in this area like lizards, birds and insects can accommodate.  

Deserts biomes reach temperatures of 40 degrees daily and receive only 250 mm yearly which is less than 10% the amount of rain a rainforest receives. These abiotic factors contribute to hostile living conditions for flora and fauna as they need water and sunlight to grow, survive and reproduce but without a constant stream of water vegetation will not grow, exposing unprotected ground which will dry out in the sunlight and heat, burning the ground. A 'desert' is classified as 'A barren area of landscape where little precipitation occurs' , this also applies to polar regions which are referred to as 'Polar deserts', other classifications which denote the term 'Dessert' are determined by the prevailing temperature or by their geographical location.

In the Sahara desert vegetation can grow but will have a stunted growth due to the temperatures offering small habitats for rodents, insects and reptiles.

The Antarctic is characterised as a polar or 'cold desert' and is the largest desert in the world covering the continent of Antarctica with temperatures ranging from -90 up and is the complete opposite to  the Sahara Desert but similar in the fact it offers hostile living environments to animals without thick layers of fat, blubber or a suitable heat source.
