Abstract

Understanding ecology is very important to the understanding of Earth’s future. It provides the basis for considerable utilization of natural resources facilitating in the conservation of habitats and species, and also for the prediction on reflection of man’s activities on natural environment. This clearly explains that ecology is concerned with relationships between living organisms: plants, animals, microorganisms and their environment. Ecologists study the way in which organisms, populations, communities and ecosystem’s function and in doing so encompass many other areas of knowledge. Understanding how our living environment works is essentially a study of ecological systems. Ecology is the science of how organisms interact with each other and with their environment, and how such interactions create self-organizing communities and ecosystems. This science touches us all. The food we eat, the water we drink, the natural resources we use, our physical and mental health, and much of our cultural heritage is to a large degree product of ecological interactions of organisms and their environment.
