Ecology is the study of organisms, populations, and communities as they relate to one another and interact in the ecosystems they comprise. Ecology is the study of the interactions of living organisms with their environment. Within the discipline of ecology, researchers work at four specific levels, sometimes discretely and sometimes with overlap. These levels are organism, population, community, and ecosystem. In ecology, ecosystems are composed of dynamically-interacting parts, which include organisms, the communities they comprise, and the non-living abiotic components of their environment.

Ecology is the study of the interactions of living organisms with their environment. One core goal of ecology is to understand the distribution and abundance of living things in the physical environment. Attainment of this goal requires the integration of scientific disciplines inside and outside of biology, such as biochemistry, physiology, evolution, biodiversity, molecular biology, geology, and climatology. Some ecological research also applies aspects of chemistry and physics, and it frequently uses mathematical models. Climate change can alter where organisms live, which can sometimes directly affect human health. When a discipline such as biology is studied, it is often helpful to subdivide it into smaller, related areas.

Ecosystem , the complex of living organisms, their physical environment , and all their interrelationships in a particular unit of space. A brief treatment of ecosystems follows. For full treatment, see biosphere. An ecosystem can be categorized into its abiotic constituents , including minerals , climate , soil , water , sunlight , and all other nonliving elements, and its biotic constituents, consisting of all its living members. Linking these constituents together are two major forces: the flow of energy through the ecosystem, and the cycling of nutrients within the ecosystem. The fundamental source of energy in almost all ecosystems is radiant energy from the Sun. Consisting largely of green vegetation, these organisms are capable of photosynthesis i.

At any given point of time do you find yourself to be surrounded by nature, with all its beauty in the form of trees , plants , lakes, rivers , animals , insects etc.? Do you think there is some form of contact or collaboration between the living and the nonliving components of ecosystem?

Ecosystems describe the web or network of relations among organisms at different scales of organization. Since ecology refers to any form of biodiversity , ecologists research everything from tiny bacteria's role in nutrient recycling to the effects of tropical rain forest on the Earth's atmosphere. The discipline of ecology emerged from the natural sciences in the late 19th century. Ecology is not synonymous with environment, environmentalism, or environmental science. Like many of the natural sciences, a conceptual understanding of ecology is found in the broader details of study, including:.

Topics of interest include the biodiversity , distribution, biomass , and populations of organisms, as well as cooperation and competition within and between species. Ecosystems are dynamically interacting systems of organisms , the communities they make up, and the non-living components of their environment. Ecosystem processes, such as primary production , pedogenesis , nutrient cycling , and niche construction , regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits. Ecology is not synonymous with environmentalism , natural history, or environmental science.



Ecology/Ecosystems

The environment is the sum total of all conditions and influences that affect the development and life of all organisms on earth. - An ecosystem can be described simply as the collection of all living and non-living components in a particular area.

    20 A fundamental concept of ecology is that living organisms (1) are independent and do not interact with each other or with the physical environment (2) do not.
