Ecology was originally defined in the midth century, when biology was a vastly different discipline than it is today. The scientific study of the processes influencing the distribution and abundance of organisms, the interactions among organisms, and the interactions between organisms and the transformation and flux of energy and matter.

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. Ecologists often collaborate with other researchers interested in ecological questions. Describe the levels of ecology that would be easier for collaboration because of the similarities of questions asked.

Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them. Ecologists study these relationships among organisms and habitats of many different sizes, ranging from the study of microscopic bacteria growing in a fish tank, to the complex interactions between the thousands of plant, animal, and other communities found in a desert. Ecologists also study many kinds of environments. For example, ecologists may study microbes living in the soil under your feet or animals and plants in a rain forest or the ocean. The many specialties within ecology, such as marine, vegetation, and statistical ecology, provide us with information to better understand the world around us.

What Is Ecology?

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 studied at many levels, including organism, population, community, ecosystem, One core goal of ecology is to understand the distribution and abundance of living things in the What are the main factors behind this change in abundance? ecologists draw on many areas of biology and related disciplines.

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.

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 or strictly natural history.

The Scope of Ecology

 Лаборатория вне закона? - спросила Сьюзан.  - Это что за фрукт. Соши пожала плечами. - Открыть. Ну и ну, - ужаснулась .

What is ecology?

Но нам известно, где. - И вы не хотите ничего предпринять. - Нет. Он подстраховался - передал копию ключа анонимной третьей стороне на тот случай… ну, если с ним что-нибудь случится. Это можно было предвидеть, - подумала Сьюзан.

Сьюзан закрыла дверь и подошла ближе. Голоса заглушал шум генераторов. Казалось, говорившие находились этажом ниже.

Дверь высотой в шесть метров закрылась с гулким стуком, и Беккер оказался заперт в Божьем доме. Он закрыл глаза и постарался сползти на скамье как можно ниже: он единственный в церкви был не в черном. Откуда-то донеслись звуки песнопения. В задней части церкви между скамьями продвигался человек, стараясь держаться в тени.

 - спросил немец с расширившимися от страха глазами. - Или мы придем к соглашению. - Какому соглашению? - Немец слышал рассказы о коррупции в испанской полиции.
