The bio-diversity of the Arctic and the Sahara are minute compared with the high levels of biodiversity that the rainforest possesses, the Arctic and the Sahara are placed in regions where the conditions for a living organism to survive and nurture is harsh and ruthless. Suitable environmental conditions are the ideal regions in which living organisms should live in as it allows generations of that particular organism to settle down and adapt to the environment even more with the species being able to expand and increase in population. The Arctic, Sahara and the rainforest are completely different ecosystems and I will explain …show more content…
The Sahara’s climate is heat in the day but incredibly cold at night which puts off many organisms from living in the desert with only a few animals with skin which can reflect the rays and absorb a small amount , have a prolonged water supply to stop dehydration, be able to cope with the heat and the cold with finally being able to find a source of food as plants in desert cannot survive long with cacti being the main plant. Cacti have long roots to find new sources of water with heat from the sunlight not being able to fully evaporate the water content in the cacti with the cacti being able to preserve water for emergency situations. The Sahara’s hot conditions limits the amount of water , food and organisms in the desert as only a few with special adaption such as camels and cacti who have built up and increase their adaptability with the desert’s climate. Subsequently , the desert provides an unstable habitat with the constant need for survival as the Sahara’s heat is all year around with small periods of
