Different animal species occupy different environments due to existence of favourable and life supporting conditions. The specific area occupied by given animal species is referred to as habitat. A habitat is made up of both living organisms and natural features. The specific weather and natural conditions in a given habitat attracts different animals to live in it. As a result, animals have adaptations to help them survive in their respective habitat. We are going to look at what types of environments do animals live in around the world.
Water occupies 75 per cent of the total earth space; this makes it the largest habitat on earth. Aquatic environment refer to different water bodies covering the earth like rivers, lakes, swamps, oceans and seas. Aquatic environment is further subdivided to salt and fresh water bodies. Salt water bodies are made up of lakes and oceans and forms the largest part of aquatic environment. Salt water is home to a variety of animals, ranging from smallest size like plankton to the largest animals on earth like the blue whale. Fresh water bodies are made up of rivers, swamps and lakes; it is home to variety of fish species and other aquatic organisms.
Desert is an extensive piece of dry land characterised by very minimal precipitation, wide temperature variations and hostile living condition. Deserts are classified according to the amount of precipitation per year. Deserts are not always covered by sand and experiencing hot temperatures as depicted in the television shows. There are deserts covered by stones while others experience very cold temperatures like the Antarctica. Animals living in the deserts have special water conservation and temperature control adaptations to help them survive in the harsh environment. Examples of animals found in the desert include camels, bats, deer and wild dogs.
Forest habitat is characterised by tree and vegetation cover with varying climatic and temperatures patterns. Tree is important to the world since it uses carbon di oxide to make food and releases oxygen to the atmosphere. Worlds’ forest can be classified into three categories; boreal forest, tropical rainforest and temperate forests. Boreal forest is located in the northern hemisphere and is characterised by cold temperatures; animals found here include birds, wolves and bears. Tropical rainforests are located along the equator; it is home to majority of wild animal species. Temperate forest is located towards the north and south hemispheres.
Grassland environment occupies an extensive area on earth; the average precipitation is between 250 and 750 millimetres per year. It is covered by extensive grass, shrubs and few trees due to the limited rainfall. It is home to different species of birds and herbivores that directly feed on fruits from the trees, grass and shrubs. Carnivores are also found in the grasslands since they feed on herbivores.
Tundra is the coldest of all the habitats, it is characterised by extremely low temperatures and short summers. Low temperatures make it hard for vegetation to grow; the ground is covered by short vegetation, shrubs and grass. Tundra can further be sub divided to artic and alpine tundra. Arctic tundra is found just below the northern hemisphere with low temperatures of up to negative 34 degrees Celsius during winter. Animals found in arctic tundra include polar bears, arctic hares and lemmings. Alpine tundra refers to the tall mountain-top environments; animals found here include elk and mountain goats.
