Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment.

Ecosystems are habitats within biomes that form an integrated whole and a dynamically responsive system having both physical and biological complexes.

Ecosystems are broadly categorized as terrestrial, freshwater, atmospheric, or marine.

Ecosystems are controlled both by external and internal factors.

Ecosystems are dynamic entities — invariably, they are subject to periodic disturbances and are in the process of recovering from some past disturbance.

Ecosystems in similar environments that are located in different parts of the world can end up doing things very differently simply because they have different pools of species present.

Ecosystems continually exchange energy and carbon with the wider environment ; mineral nutrients, on the other hand, are mostly cycled back and forth between plants, animals, microbes and the soil.

Ecosystems are composed of a variety of abiotic and biotic components that function in an interrelated way.

Ecosystems receiving more nitrogen than the plants require are called nitrogen-saturated.

Ecosystems are no different than other bodies economically except insofar as they are far less replaceable than typical labour or commodities.

Ecosystems in and around the urban center are especially influenced by these point sources of pollution.

Ecosystems are regenerative as well.

A feature distinguishing it from prior economic regimes is the direct valuation of natural capital and ecological services as having economic value ( see The Economics of Ecosystems and Biodiversity and Bank of Natural Capital ) and a full cost accounting regime in which costs externalized onto society via ecosystems are reliably traced back to, and accounted for as liabilities of, the entity that does the harm or neglects an asset.

Further, DOP / UAç are participants in Steering Committees for three great initiatives by Census of Marine Life program: ChEss ( Biogeography of Chemosynthetic Ecosystems ), MAR-ECO ( Patterns and Processes of the Ecosystems of the Mid-Atlantic Ridge ) and CenSeam ( A Global Census of Marine Life on Seamounts ).

Although pig-nosed turtles are protected in Indonesia under Law No. 5 / 1990 on Natural Resources and Ecosystems Conservation, smuggling occurs.

* Pelagic Ecosystems Department, which studies the ecology of plankton with regard to sea ice and sea shelf systems.

Ecosystems in the deep sea, where no sunlight can penetrate, use sulfur.

Ecosystems regenerate after a disturbance such as fire, forming Mosaic ( ecology ) | mosaics of different age groups structured across a Landscape ecology | landscape.

He first came to public prominence as an environmental consultant at the time of the 1967 Torrey Canyon disaster ; he published Effects of Pollution from the Torrey Canyon on Littoral and Sublittoral Ecosystems in Nature.

The-long Iceberg B-15, the largest ever seen at the time, broke off from the Ross Ice Shelf in March 2000 ( Antarctic Climate & Ecosystems: Cooperative Research Center ).

Since that time Dr. Church has led a number of programs with CSIRO Division of Oceanography and was Program Leader of the Oceanography Program ( now non-existent ), Australian National Antarctic Research Expeditions ; former Project Leader, Leader, Southern Ocean Processes Project ( now non-existent ), CSIRO Division of Marine and atmospheric Research, Polar Waters Program ( now-non-existent ), Antarctic Climate and Ecosystems Cooperative Research Centre.

Ecosystems maintain biophysical feedback mechanisms that modulate metabolic rates and evolutionary dynamics between living ( biotic ) and nonliving ( abiotic ) components of the planet.

Ecosystems sustain life-supporting functions and produce natural capital through the regulation of continental climates, global biogeochemical cycles, water filtration, soils, food, fibres, medicines, erosion control, and many other natural features of scientific, historical, economic, or intrinsic value.

Ecosystems, for example, contain populations of individuals that aggregate into distinct ecological communities.

Ecosystems provide a variety of goods and services upon which people depend ; the principles of ecosystem management suggest that rather than managing individual species, natural resources should be managed at the level of the ecosystem itself.

Accidental war is so sensitive a subject that most of the people who could become directly involved in one are told just enough so they can perform their portions of incredibly complex tasks.

Very likely it will also include a recognition that the work we are reading reflects or `` belongs to '' some way of thought labelled as a `` school '' or an `` -ism '', i.e. a complex or `` syndrome '' of ideas occurring together with sufficient prominence to warrant identification.

More importantly, several of the more advanced of the less developed countries have found through experience that they must plan their own complex investment programs for at least 5 years forward and tentatively for considerably more than that if they are to be sure that the various interdependent activities involved are all to take place in the proper sequence.

The causes of the decline of the commuter railroads are many and complex -- high taxes, losses of revenue to Government subsidized highway and air carriers, to name but two.

The problems of hard-surface cleaning are not nearly as complex.

On the other hand, there are a few antithyroid drugs of this same general type, such as resorcinol, possessing no reducing activity and possibly acting through formation of a complex with molecular iodine.

Since emotional reactions in the higher vertebrates depend on individual experience and are aroused in man, in addition, by complex symbols, one would expect that the hypothalamus could be excited from the cortex.

If we are discussing differentiable complex-valued functions, then Af and V are complex vector spaces, and Af may be any complex numbers.

We now write Af where Af are distinct complex numbers.

In considering roleplaying for analysis we enter a more complex area, since we are now no longer dealing with a simple over-all decision but rather with the examination and evaluation of many elements seen in dynamic functioning.

In sentences, patterns of stress are determined by complex combinations of influences that can only be suggested here.

Tone systems are certainly more complex than the number of units would suggest, and often analytically more difficult than much larger consonantal systems.

Wage-price policies of industry are the result of a complex of forces -- no single explanation has been found which applies to all cases.

While this influence is a complex matter, depending upon personality factors in the individual as well as upon his social-class experience, there probably are some general statements about social-class background and educational policy that can be made with a fair degree of truth.

While patent suits are still among the most complex and expensive forms of litigation, these rules have saved litigants uncounted sums of money.

( And this is not, perhaps, the place to discuss Harlem's very complex attitude toward black policemen, nor the reasons, according to Harlem, that they are nearly all downtown.

The Administration's proposals, complex and sweeping as they are, all deal with fringe areas of the housing market rather than its core, stated Caron S. Stallard, first vice-president of the Mortgage Bankers Association of America.

( 2 ) Realtors realize, of course, that they are involved in an increasingly complex legal and political system that is opening up opportunities for leverage on their relation to clients as well as opportunities for evasion of their responsibility for racial discrimination in housing.

With their often complex reproductive needs and permeable skins, amphibians are often ecological indicators and in recent decades there has been a dramatic decline in amphibian populations of many species around the globe.

With their complex reproductive needs and permeable skins, amphibians are often considered to be ecological indicators.

The largest and most complex marine forms are called seaweeds.
