Habitat
A biome is a place where a plant or animal live. Biome also known as habitat is a part of an ecosystem. The climate, plants, and animals are the identities of a habitat. Habitats are classified into two domains: Terrestrial/ Land habitat and Aquatic/Water habitat. Land habitat includes forests, grasslands, deserts, coastal and mountain regions.The aquatic ecosystem includes freshwater habitats (lakes, ponds, rivers and streams, wetlands, swamp, etc) and marine habitats (oceans, intertidal zone, reefs, seabed, etc.). Living organisms live on different habitats depend on that habitat for their food, shelter, reproduction and all other life activities.
Adaptation
A habitat consists of two components biotic and abiotic components. All living organisms in a habitat are considered to be the biotic components of a habitat while all non-living things like rocks, soil, water, etc are abiotic components. These components determine the number and type of species existing in a region. But all habitats do not provide living organisms all of these components while others may provide more than enough. Therefore, they have to evolve and adopt certain behavior or structural modifications. These physiological, behavioral and morphological patterns differ from region to region as per conditions of that terrain.
Adaptation is the modifications in either physical, behavioral or both characteristics in an organism in order to live in its habitat. These are the outcome of changes in biotic and abiotic components over thousands of years. In the case of aquatic animals, they can’t survive outside water. Hence, they need to adapt themselves to live in their habitat. Hence, the majority of aquatic animals are streamlined which helps them to reduce the friction and thus save energy. They have fins and gills as their locomotory and respiratory organs respectively.
Adaptation is the evolution or approaches adopted by different organisms to ensure their continuance. It supports life even in bleak conditions. Adaptations are unique to a particular area and these adaptations will not be effective in other areas. This explains why some plants or animals are unique to a region and why they cannot exist in other habitats.
