Introduction to the Ecosystem Concept Introduction In topic , an ecosystem was defined as a dynamic entity composed of a biological community and its associated abiotic environment. Often the dynamic interactions that occur within an ecosystem are numerous and complex. Ecosystems are also always undergoing alterations to their biotic and abiotic components. Some of these alterations begin first with a change in the state of one component of the ecosystem which then cascades and sometimes amplifies into other components because of relationships. In recent years, the impact of humans has caused a number of dramatic changes to a variety of ecosystems found on the Earth. Humans use and modify natural ecosystems through agriculture, forestry, recreation, urbanization, and industry. The most obvious impact of humans on ecosystems is the loss of biodiversity . The number of

The term ecosystem was coined in 1935 by the British ecologist Sir Arthur George Tansley, who described natural systems in “constant interchange” among their living and nonliving parts. The ecosystem concept fits into an ordered view of nature that was developed by scientists to simplify the study of the relationships between organisms and their physical environment, a field known as ecology . At the top of the hierarchy is the planet’s entire living environment, known as the

Ecosystems Solar System Human Body Systems Government Systems ... Miscellaneous Systems Ecosystem What exactly is an ecosystem? How is it different from a biome? Here is one way to think about it: Individual plants or animals living together are called a population. Several populations are called a community. Several communities form an ecosystem. Ecosystems sharing the same climate make up a biome. All earth's biomes form the biosphere. What these groups all have in common is interdependence. Living things do not exist in isolation. They constantly interact with each other and with their environment and are dependent upon each other for survival. The parts that make up an ecosystem are plants, animals, and the environment in which they live, including soil, air, water, sunlight, minerals, and nutrients. All of these parts interact in energy and nutrient cycles. Enemies to ecosystems are human activity and pollution. How we interact with an ecosystem can have impact thousands of miles away. For example, monarch butterflies that live across the United States migrate to parts of California and Mexico during the winter. In California, many sites historically frequented by monarchs have been destroyed by human development. Destroying habitat in California could potentially bring about monarch butterfly decline throughout North America. Sample some of the following activities to learn more about ecosystems.

Controlling Human Impact on Ecosystems I Introduction Printer-friendly version of section Ecosystem , a relatively self-contained, dynamic system composed of a natural community along with its physical environment. The concept, first developed in the 1920s and 1930s, takes into account the complex interactions between the organisms—plants, animals, bacteria, and fungi—that make up the community and the flows of energy and matter through it. Ecosystems can be classified in many different ways and the term itself is used in a variety of contexts. Areas as small as intertidal rock pools and as large as entire rainforests can both be described as ecosystems. However, it is generally not possible to state with precision where one ecosystem ends and another begins. The notion of rigidly separable ecosystems is thus a largely artificial one.
