The tundra is characterized by extreme cold and a short growing season, which results in very low species diversity compared to forests or grasslands.

Depending upon area type where organisms live, terminology is used.

cultivated land need to be protected from the grazing animals.

Hydrophytes grow in water. Mesophytes growin moderate conditions. Epiphytes are weeds.

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.
