The Eco System

Introduction

An ecosystem is a biological environment that consists of all the organisms living of a particular place, including all of the non-living components (biotope), the physical components of the environment in which organisms interact, such as air, soil, water and sunlight.

The concept, which began to develop between 1920 and 1930, takes into account the complex interactions between organisms (egg plants, animals, bacteria, protests and fungi) that form the community (biocenosis) and flows of energy and materials that cross. Central to the ecosystem concept is the idea that living organisms interact with any other element in its local environment.

Energy Flow

The flow of energy is used by primary producers or agencies organic compounds which, in turn, use the consumer's primary or herbivores, which feed the secondary consumers or carnivores. The bodies of all groups, the decomposers can obtain the power to make ends meet. Thus is obtained a unidirectional flow of energy at which the energy passes from one level to another in one direction and provided with a loss in the form of heat. Energy is the capacity to do work and behavior describes the same laws of thermodynamics, which are two:

The first law states that energy can be transformed from one type to another, but not be destroyed. for example, the light energy is converted into organic matter (wood), which in turn is converted to heat (fire) and light, the heat can be converted into motion energy (steam engines), this in light (generator that produces electricity), and so on.

The second law says that when moving from one energy form to another (chemical mechanical energy into heat and vice versa) is lost as heat energy. Any change of a form of energy to another heat losses occur. It follows that ...
