Unifying Concepts in Ecology pp Cite as. This paper has been conceived from a background of European phytosociology and plant ecology, involved in the study of the vegetation of more or less densely populated countries like the Netherlands. I want to speak on behalf of many colleagues from that field of ecology.

Natural and Man Made Ecosystem

Every one of us is sustained by various kinds of natural resources — such as food, materials, and energy that are harvested or otherwise extracted from the environment. Our need for those resources is absolute — we cannot survive without them. Moreover, the same is true of all other species — every organism is a component of an ecosystem that provides the means of subsistence. Collectively, the needs and activities of people comprise a human economy. That economy operates at various scales, ranging from an individual person, to a family, to communities such as towns and cities, nation-states such as Canada , and ultimately the global human enterprise. While an enormous and rapidly growing number of people are supported by the global economy, a lot of environmental damage is also being caused. The most important of the damages are the depletion of vital natural resources, various kinds of pollution including climate change , and widespread destruction of natural habitats to the extent that the survival of many of the natural ecosystems and species of Earth are at grave risk.

A natural ecosystem has a diverse amount of species and plants, whereas artificial ecosystems are limited. Natural ecosystems are self-sustaining and result.

Managing Our Man-Made Ecosystems

In modern society, buildings are where we spend the vast majority of our waking and sleeping hours. Our facilities are man-made ecosystems—vast assemblages of interdependent living and non-living components. Facilities have become the primary habitat for the human species. As technology advances at a record pace, our man-made ecosystems are becoming ever more complex and sophisticated.

The Tragic Effects of Man Made Disasters

View all blog posts under Articles. Disasters are unfortunate events that almost always end in the loss of life and destruction of property. They happen randomly and suddenly, and have been occurring since before recorded time — well at least natural disasters like earthquakes, floods, landslides, hurricanes and tornadoes. It was only a couple of hundred years ago with the invention of industry that people brought about unnatural man-made disasters. Natural disasters are dictated by natural forces that people have little to no influence over.

Objective a. Describe natural biodiversity and man-made biodiversity in ecosystem b. Differentiate natural from man-made biodiversity in ecosystem c.

Simple Ecosystem Definition

Ecosystems are functional units consisting of living things in a given area, non-living chemical and physical factors of their environment, linked together through nutrient cycle and energy flow. Image Curtsey: thiele-und-thiele-consult. These operate by themselves under natural conditions without any major interference by man. Based upon the particular kind of habitat, these are further divided as:. The forests are natural plant communities with dominance of flowering plants. Trees, shrubs, herbs and climbers are present in plenty. Some examples of forest ecosystem are:.

An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. By feeding on plants and on one another, animals play an important role in the movement of matter and energy through the system. They also influence the quantity of plant and microbial biomass present. By breaking down dead organic matter , decomposers release carbon back to the atmosphere and facilitate nutrient cycling by converting nutrients stored in dead biomass back to a form that can be readily used by plants and other microbes. Ecosystems are controlled by external and internal factors. External factors such as climate , parent material which forms the soil and topography , control the overall structure of an ecosystem but are not themselves influenced by the ecosystem.
