Ecologists study many diverse and complex relations among species, such as predation and pollination. The diversity of life is organized into different habitatsfrom terrestrial middle to aquatic ecosystems.
It is an interdisciplinary field that includes biologygeographyand Earth science. Ecology includes the study of interactions organisms have with each other, other organisms, and with abiotic components of their environment.
Topics of interest to ecologists include the diversitydistribution, amount biomassand number population of particular organisms, as well as cooperation and competition between organisms, both within and among ecosystems.
Ecosystems are composed of dynamically interacting parts including organismsthe communities they make up, and the non-living components of their environment.
Ecosystem processes, such as primary productionpedogenesisnutrient cyclingand various niche construction activities, regulate the flux of energy and matter through an environment. These processes are sustained by organisms with specific life history traits, and the variety of organisms is called biodiversity.
Biodiversitywhich refers to the varieties of speciesgenesand ecosystemsenhances certain ecosystem services. Ecology is not synonymous with environment, environmentalismnatural history, or environmental science. It is closely related to evolutionary biologygeneticsand ethology.
An important focus for ecologists is to improve the understanding of how biodiversity affects ecological function.
Ecologists seek to explain: Life processes, interactions, and adaptations The movement of materials and energy through living communities The successional development of ecosystems The abundance and distribution of organisms and biodiversity in the context of the environment.
Ecology is a human science as well.

For example, the Circles of Sustainability approach treats ecology as more than the environment 'out there'.
It is not treated as separate from humans. Organisms including humans and resources compose ecosystems which, in turn, maintain biophysical feedback mechanisms that moderate processes acting on living biotic and non-living abiotic components of the planet.

Ecological thought is derivative of established currents in philosophy, particularly from ethics and politics. Modern ecology became a much more rigorous science in the late 19th century. Evolutionary concepts relating to adaptation and natural selection became the cornerstones of modern ecological theory.
Levels, scope, and scale of organization The scope of ecology contains a wide array of interacting levels of organization spanning micro-level e.
Ecosystems, for example, contain abiotic resources and interacting life forms i. Ecosystems are dynamic, they do not always follow a linear successional path, but they are always changing, sometimes rapidly and sometimes so slowly that it can take thousands of years for ecological processes to bring about certain successional stages of a forest.
An ecosystem's area can vary greatly, from tiny to vast. A single tree is of little consequence to the classification of a forest ecosystem, but critically relevant to organisms living in and on it.
Each of those aphids, in turn, support diverse bacterial communities. Biological organisation and Biological classification System behaviors must first be arrayed into different levels of organization.Turing did not originally claim that physical system producing patterns actually performed computation through morphogenesis.
Nevertheless, from the perspective of info-computationalism (Dodig Crnkovic ) we can argue that morphogenesis is a process of morphological computing. A related issue is whether scanning methods for the necessary.
