It is a very dry habitat with water shortages. The plants are called as xerophytes. They have diverse forms and undergo structural and physiological adaptations or modifications to reduce the rate of transpiratio..

Lamarck suggested that new needs arise in the organisms as the ever-changing environment influences them. Changes in the environment create a new need in the organism for adapting to that change, failing which the organism cannot surviv..

Some organisms have become secondarily adapted for aerial existence. Organisms that are capable to do their activities in the aerial environment are called as aerial or arboreal organisms..

Every organism whether plant or animal is unique in itself. There is a wide diversity in the flora (plants) and fauna (animals) in the world. The diversity we see today is the result of 3.5 billion years of organic evolution. During the course of this evoluti..

Environment includes all the factors that affect the form and growth of the organism. Habitat is the term given to the special environment in which an organism lives and grows. In order to survive, plants and animals develop special features called adaptive chara..

The body is boat shaped or stream lined. Aquatic Adaptations in Fish Head, body and tail are compressed to make it suitable for locomotion in water, so that it offers little or no resistance for swimming in wat..

Old and inefficient organs are replaced by young and developing organs. Leaf fall in deciduous trees reduces the rate of transpirational loss. This is an adaptation to tide over winte..

>Fossils also show evidences of evolutionary relationships. Their study provide knowledge about the extinct forms, and also provide links between two groups of species Organisms have emerged due to evolution by stages and adaptations for new functions. Intermediate stages can be..
