Also referred to as population regulation, it means the total of all inhibitory factors naturally regulating the growth of population. The environment puts up its resistance after a level often less than biotic potential or even carrying capacity. Such resistance may be in the form of ..

>A healthy environment is an absolute necessity for the well-being of all organisms, including man. All our needs, big and small are being met by the environment. However, man having reached the pinnacle of evolution is trying to bring about changes in the environ..

This is the domain of living organisms in contact with atmosphere, hydrosphere as well as lithosphere. Man has begun to effect significant changes in his natural environment mainly after the advent of the Industrial revolution. The change in industrial and agricultura..

Animals are different from plants because of their ability of locomotion. This ability probably developed as they have to search for food, unlike the plants that are autotrophic. Since they move from one place to another, the animals have to continuously encounter changes in their h..
