Discuss in detail various adaptations found in plants and animals in snowy winter of polar regions.
Adaptations in plant and animals of polar regions: Organisms living in polar regions have to face the severe snowy winter and show entirely different types of adaptations. Animals in polar regions are generally white or tight coloured. This light colouration helps in camouflage and in thermal regulation. During extreme winter they undergo hibernation. Animals eat a lot of food during summer and autumn and store a lot of energy in the form of fat. During hibernation, their metabolic activities are reduced considerably, The plants growing in these regions remain dormant during extreme winter months. They bear narrow leaves, spines, etc. which are shed easily and rapidly, Plants remain dwarf. Trees are usually not found in these regions as they cannot withstand the low temperatures.
