diversity and adaptations of organisms

Vegetation in tundra is very sparse. Hence, it is also called 'arctic desert'. It exhibits very low species diversity. a) Biome is virtually treeless and is comprised of only Lichens (Cladonia - Reindeer moss) and Mosses (Sphagnum - Peat moss) forming the main vegetation. b) Other plants ..

. Speciation does not intend to convey the dieing out of one inferior species giving way to superior ones. Species adapt to the conditions available in their environment. Some older and simple species live on quite effectively. The scorpion, is one of the more primitive invertebrate which..

The habitat and adaptation have a very strong relationship and a perfect balance must be maintained for the survival of the organism. Due to natural calamities and human activities the habitat often gets altered. These alterations may be permanent or temporar..

Many of the worlds habitats and ecosystems depend on a delicate balance of rainfall, temperature and soil type. A complex food chain supply exists based on these factors. Higher temperatures and precipitation changes are likely to cause diverse changes such as increased forest susceptibi..

Man is omnivorous - feeding on different kinds of food. Thus, the structure of the digestive system should be adapted to this diet. The human digestive system consists of an alimentary canal, which is approximately 8metres long. The alimentary canal also carries out absorption of the dige..

Significance of Senescence - i) Old and inefficient organs are replaced by young and developing organs. ii) Leaf fall in deciduous trees reduces the rate of transpirational loss. This is an adaptation to tide over winter. iii) Recovery of nutrients from senescing ..
