Natural Vegetation and Habitats

Endangered species are those which are o he verge of becoming extinct. Threatened species are those which are likely to disappear from this world and extinct species are those which have disappeared from this world.

Biodiversity is the degree of variation of life. It is a measure of the variety of organisms present in different ecosystems.

Lotus is generally seen growing on the surface of ponds which do not have fast water current.

Animals and plants that live on the land are known as terrestrial animals. However, the animals like fish, whales, sharks live in water and are known as aquatic animals

Habitat of animals and plants in different regions depends upon their body structure and its adaptability. E.g. animals like Yak, Lions, ants live on ground and are known as terrestrial animals. Forests, grounds, grasslands, deserts are all include in terrestrial habitat whereas ponds, swanks lakes, rivers, sea, ocean in the aquatic habitat.

Different kinds of plants are found in different regions because of the reason that survival of different plants in a particular area depends upon many factors like climate, soil texture, organisms found over there. All these factors are collectively divided into 2 major categories; the living factors as biotic and non living ones as abiotic.

The upper layers of sand are comparatively at a very high temperature as compared to the lower layer which are at a low temperature. Thus the animal like snakes live in deserts by digging deep burrows.

Different animals and plants have habitant in different regions depending upon their body structure and their adaptability. E.g. animals like Yak, Lions, ants live on ground and are known as terrestrial animals.        Animals like fish, whales, sharks live in water and are known as aquatic animals. Crab is an animal        which is generally found on the sea shores or beaches as it is neither completely terrestrial nor aquatic.

Different places are having different climatic conditions and thus variety of flora and fauna. For e.g. terrestrial habitat refers to grounds, grasslands, etc. Arboreal refers to staying on trees like monkeys. Xeric refers to deserts having hot and dry climatic conditions and aquatic as the water bodies.

The land on which the grass grows is said to be grassland - Zebra, Lions and giraffes are suited well to stay on the grassland. Thus, all the given organisms are inhabitant of grasslands

Talipot palm bears 6-8 m long branched inflorescence having millions of flowers.

Moist habitats are most suitable for bryophytes.

The Steppes are the vast temperate grasslands that stretch across Eurasia, from Eastern Europe to Central Asia.

Tarn lakes are small mountain lakes formed in a cirque excavated by a glacier. They are typically found in temperate highland regions where glacial activity has occurred.

As forests help in purification of air.
