It takes millions of years for a stable community to develop but the rapid pace of mechanized development and extensive use of chemicals destroy or wipe off full ecosystems very rapidly.

A species or an organism can never live alone. They are always influencing each other and organizing themselves into communities, besides they have functional relationship with their external environment.
We are all familiar with the process of competition as we ourselves face it in various ways in our day-to-day life. Competition occurs in nature generally, but not necessarily, when resources like food, space, mates are limited.
With the help of the following flow chart, we can interpret the functional aspect, an ecosystem, or the interactions between various components, which involve the flow of energy, and cycling of materials.
The existing natural ecosystem is often confronted with negative impacts of modern technology. These often cause stress, especially by altering the fundamental stability of an ecosystem.
In this article, we will discuss about different types of ecosystems on our earth. Broadly speaking, there are two major types of ecosystems: the aquatic and the terrestrial.
One fascinating attribute of an ecosystem is the diversity of species that make up the system. A diversity of functional groups is naturally to be expected because the food webs in an ecosystem involve autotroph, herbivores, carnivores, detritivores, and so on.
The term ‘energy’ is quite familiar to us and we use it in a very general sense. Often this usage does not correspond to the precise scientific definition. It is, therefore, important to first define it precisely.
Flow of energy through the ecosystem is a fundamental process, which can be easily quantified if the energy input to the ecosystem and its subsequent transformation from one tropic level to another can be expressed in terms of calories.
Water cycle is another important material cycle. Water is one of the important substances necessary for life. On average water constitutes 70% of the body weight of an organism.
