Habitat of an organism is its immediate surroundings. Habitat is the home of the organism where it can find food, shelter and favourable conditions for breeding. Habitat includes both living and non-living components.Plants and animals possess special characters which help them to survive in their own habitat. Biotic components include all the livings organisms in a habitat, i.e. plants, animals and microorganisms. 2  Abiotic components include all the non-living things in a habitat, i.e. air, soil, water, sunlight and temperature. 3  The favourable conditions for survival of living organisms are provided by abiotic components.
Casein in Foods. Most dairy products contain casein, but not all. Since casein is a protein, it is found in dairy products that have a higher protein content, such as milk, yogurt, kefir, cheese and ice cream. Dairy products that contain barely any protein, such as butter and cream, only have traces of casein.
