    (Ecology is sometimes used incorrectly as a synonym for the natural environment or environmentalism.)

    Ecology is essentially the study of the Earth's organisms and their relationships with their abiotic and biotic environments.Ecology or ecological science, is the scientific study of the distribution and abundance of living organisms and how these properties are affected by interactions between the organisms and their environment. The environment of an organism includes both the physical properties, which can be described as the sum of local abiotic factors like climate and geology, as well as the other organisms that share its habitat.

    Ecology may be more simply defined as the relationship between living organisms and their abiotic and biotic environment or as "the study of the structure and function of nature" (Odum 1971). In this later case, structure includes the distribution patterns and abundance of organisms, and function includes the interactions of populations, including competition, predation, symbiosis, and nutrient and energy cycles.

    The term ecology (oekologie) was coined in 1866 by the German biologist Ernst Haeckel. The word is derived from the Greek oikos ("household," "home," or "place to live") and logos ("study")—therefore, "ecology" means the "study of the household of nature." The name is derived from the same root word as economics (management of the household), and thus ecology is sometimes considered the economics of nature, or, as expressed by Ernst Haeckel, "the body of knowledge concerning the economy of nature" (Smith 1996).

    The interactions between living organisms and their abiotic and biotic environments, the focus of ecology, generally convey an overall sense of unity and harmony in nature. See for instance, species interactions. On the other hand, the history of the science itself has often revealed conflicts, schisms, and opposing camps, as ecologists took different approaches and often failed

    Ecology is usually considered a branch of biology, the general science that studies living and once-living organisms. Organisms can be studied at many different levels, from proteins and nucleic acids (in biochemistry and molecular biology), to cells (in cellular biology), to multicellular systems (in physiology and anatomy, to individuals (in botany, zoology, and other similar disciplines), and finally at the level of populations, communities, and ecosystems, and to the biosphere as a whole. These latter strata, from populations to the biosphere, are the primary subjects of ecological inquiries.

    The complexity of the subject of ecological studies can be see in this river in South America, which is part of the world's largest wetland, the Pantanal.Ecology is a multi-disciplinary science. Because of its focus on the higher levels of the organization of life on earth and on the interrelations between organisms and their environment, ecology draws heavily on many other branches of science, especially geology and geography, meteorology, pedology, chemistry, and physics. Thus, ecology is said to be a holistic science, one that overarches older disciplines, such as biology, which in this view become sub-disciplines contributing to ecological knowledge.

    Agriculture, fisheries, forestry, medicine, and urban development are among human activities that would fall within Krebs' (1972: 4) explanation of his definition of ecology: "where organisms are found, how many occur there, and why."

    The term ecology is sometimes confused with the term environmentalism. Environmentalism is a social movement aimed at the goal of protecting natural resources or the environment, and which may involve political lobbying, activism, education, and so forth. Ecology is the science that studies living organisms and their interactions with the environment. As such, ecology involves scientific methodology and does not dictate what is "right" or "wrong." However, findings in ecology may be used to support or counter various goals, assertions, or actions of environmentalists.

    Consider the ways an ecologist might approach studying the life of honeybees:

    The behavioral relationship between individuals of a species is behavioral ecology—for example, the study of the queen bee, and how she relates to the worker bees and the drones.

    The organized activity of a species is community ecology; for example, the activity of bees assures the pollination of flowering plants. Bee hives additionally produce honey, which is consumed by still other species, such as bears.

    The relationship between the environment and a species is environmental ecology—for example, the consequences of environmental change on bee activity. Bees may die out due to environmental changes. The environment simultaneously affects and is a consequence of this activity and is thus intertwined with the survival of the species.

    Ecology is a broad science which can be subdivided into major and minor
