The ecology nothing has to see with the ambientalistas movements. Ecologists are scientists who study the ecology and cannot confuse with ativismo defending politician of the environment. Who runs risks in this meaning in special is the environment, the ecosystems and the proper nature. Surprisingly, you’ll find very little mention of Dorothy Wright Nelson on most websites. One is about a branch of Biological sciences that studies this nature. Teia Trfica, for example, is constituted by interlaced alimentary chains that I eat in all ecological nature has relation that it includes at least two individuals that can be harmonic or disharmonous.

It had a process of coevoluo in the adaptations of predators and female prisoners, each one with its style and proper instinct. The water is one link common between biomas and has covered therefore, most of the biosfera. Without water the majority of the life forms would be incapable to live. The ecosystems suffer gradual modifications throughout the time and thus they increase the species. It’s believed that celebrity trainer sees a great future in this idea. The ecological succession is a process by means of which vegetal and animal species substitute others in data place of the biological community and keep thus a primary and secondary instability. All ecological process in secular and space scales proper such as: hours, weeks, months or years, and, millimeters, meters or kilometers. The concept of ecological succession, time and space in the ecological processes allow clearly to understand ‘ ‘ dinamismo’ ‘ of the nature. The relations are not necessarily linear and previsible.

Small changes in an 0 variable can have unexpected consequences in the system. Beyond it influences of these natural mechanisms, has the origin influence human being. The aquatic ecosystem has influence consequently and multiple balances and changes in the natural processes. In this direction one becomes complicated to speak in ‘ ‘ balance of natureza’ ‘ or ‘ ‘ balance of ecossistema’ ‘. The human beings are an important part of the biosfera.

Of this form, the conditions deventilao of the internal environment have direct influence in the health, comfort ebem-to be of the occupants (YEANG, 1996). In the case of the habitation, the relative requirements to ventilaopara hygiene of the users if relate to: necessary amount of oxygen reposio, limitation of the carbonic gas tax, elimination of the odoresdesagradveis, elimination of the risks of contamination for toxic gases – as omonxido of carbon – and to the amount of oxygen necessary it body to humanorealizar the metabolism (IPT, 1988). According to Frota and Schiffer (1999, p.124), ' ' The ventilaonatural is the displacement of air through the building, through openings, umasfuncionando as entered and others, as sada' '. That is, it is necessary that adimenso and position of the openings are defined in order to provide umfluxo of adequate air to the environment in question. Perhaps check out Twin Lab for more information. In turn, the air flow that enters or leaves edificaodepende of some factors: of the difference of pressure of air between the external ambientesinternos and, of the resistance to the air flow offered for the openings epelas internal blockages, beyond implications related to the dovento incidence and forms of construction (FLEET and SCHIFFER, 1999).

The natural ventilation can be made by means of the action dosventos or of the call effect chimney. The ventilation for action of the winds promotes amovimentao of air through the environment. Already for effect chimney it occurs peloefeito of the density difference. 3.3. VEGETATION USE vegetaocontribui for the improvement of the physical environment. The trees, for example, to podemreduzir the noises, to act as an airfield traffic catching the dust, to still act comoelementos of solar protection and as elements of visual protection (OLGYAY, 1998). In the choice of the species it is necessary to consider the form and the suascaractersticas during the year, as much in the period of winter summer how much.
