ECOLOGY Ecology is concerned with the study of organisms and their habitats. This includes the interdependence of various populations‚ their impact on each other and their surroundings‚ the effect of the surroundings on their behaviour‚ as well as the ways in which the organisms and the environment change in response to each other. A pond and its inhabitants provide a good example of these interrelationships. A pond contains: a. soil consisting of rock‚ minerals and dead remains of organisms b. water
