what is an ecosystem ?no internet copy?

Hi, I've already answered this question here so I'll quote myself:\nEcosystem is short for ecological system. What does "system" mean in this context? A complex system is a group of elements that are inter-related; the outcome of those interelationships produces a structure and functions so that the system is more than the sum of its component parts.\nIn the case of ecosystems, the elements are biotic (living, i.e. animals, plants, fungi, etc.) and abiotic (soil, air, water, etc.). All functions and relationships among these components are also part of the ecosystem, including feeding and all types of symbioses. You can examine the structure and functions separately, but the ecosystem is a whole where every element depends on others and is depended on. There are matter, energy and information fluxes running continuously in and out of it.

the pictures are all dated differntly.  they werent all taken in one day, infact those pictures range from last week, to 5+ years ago.  google just gathered all the pictures and put them  togeather and you got the planet earth. well most of it.  and the softwere itself doesnt update itselt. but the pictures and the "earth" itself does, its pulls it directly from the server.  thats why it says its streaming and loading when you zoom in and such.

To me it is just like Yahoo's page (Geocities). Simply a place to start a website and almost never updating it.\nHaving no internet is sad...\n\n\n\n\nhttp://www.geocities.com/henry_ekkerd/\nhttp://lantere.googlepages.com/home

Absolutely not. The internet is controlled by humans, it doesn't expand on its own. It doesn't have the ability to expand on its own and it never will have the ability to learn anything. It doesn't learn. Thats like filling a pitcher with jello and saying, "Look it's a living being. It has a structure, it holds what i put into it and it wiggles when i touch it!!"

The internet is not a place, or even a thing that's located in a place.  It's not even a place, in the tangible sense.  It's just something that is.  "The internet" simply refers to the union of all the different servers out there where all the information for all the different websites you go to is stored.

A food web or food chain is just a representation of what would eat what.  To make one simple list animals making a connections from the prey to the consumer.

I dont think so.\n\nYa you have to take the internet technology into consideration and not internet persay.\n\nHow could we book our air tickets, how could we communicate with friends half way round the globe, how could we even dream of video phony?\n\nI dont think the present life can sustain without internet technology.

Diversity is a term that refers both to the different classes of items in a given system, and also to the distribution of those items in those classes.\nBiological diversity or biodiversity is related to the concept of biocomplexity, that is, the web of interelationships and fluxes circulating in the ecosystem. It is usually measured at three levels: ecological biodiversity, species biodiversity and genetic biodiversity.\n\nSpecies biodiversity is not only the number of species in a given ecosystem, but also the proportion of individuals that belong to each species. \nExample: \nIf you have 10 species, but out of a 100-individuals sample, 91 belong to a single species, then the biodiversity is not that high. In probabilistic terms, you  could say that the chances of finding 9 of the 10 species in any sample is low. \n\nThe rainforests of the world are classical examples of high diversity ecosystems. In contrast, most ecosystems that are under continuous stress are less biodiverse, for example deserts, or grasslands. However, low biodiversity does not necessarily mean "less healthy" ecosystems. Although a grassland is less biodiverse than a rainforest, it's a stable biome all the same.\nA related concept, ecological biodiversity, refers to the variety of ecosystems in a given area, and the pattern of distribution of communities in a given landscape. No ecosystem is completely isolated from others and the health of each one depends partly on the interrelationships with other areas, therefore, the loss of ecological biodiversity due to the disappearance of certain environments can lead to greater unbalances.\nGenetic biodiversity refers to variety at genetic level. In a population, it refers to the different alleles (variations of a single gene) that are present. We know that evolutionarily speaking, polymorphisms (presence of different alleles) are a sign of a healthy population, because a greater source of variation is a better resource to respond to environmental changes. Populations that lose their genetic biodiversity (for example, because the number of individuals is severely reduced) may be more exposed to extinction. \nBiodiversity can be measured at all the organization levels studied by Ecology, but is especially focused in communities and ecosystems.

There is not any special method. You can download like other stuff.

This is one of the biggest unknowns left for modern scientists to answer. Archea is such a black box. We can't even detect these guys well enough to definitively answer the question if there is a significant presence of Archea in our ecosystems -- internal or external environments -- let alone if these ancient bugs are pathogenic in any way.\n\nI'm of the camp that believes that there will probably be a lot of determined in the future that will make it much more apparent the answer to this question.\n\nBy the way, great question.

Ecosystems are about synomymous with biomes (areas of the world with similar climate, plants and animals).\n\nThere are seven kinds of biomes in the world: tundra, taiga (= coniferous forest), temperate forest, tropical rainforest, desert, grassland, and ocean. \n\nOf course, most places on the 'Net list more than 7 biomes.\nhttp://www.windows.ucar.edu/cgi-bin/tour_def/earth/ecosystems.html\nhttp://www.enchantedlearning.com/biomes/

I took this from wikipedia. It's for reference!!\n\nAn ecosystem, a contraction of "ecological" and "system", refers to the collection of components and processes that comprise, and govern the behavior of, some defined subset of the biosphere. The term is generally understood to refer to all biotic and abiotic components, and their interactions with each other, in some defined area, with no conceptual restrictions on how large or small that area can be. \nIn biology, Abiotic components are nonliving chemical and physical factors in the environment. Often, these are described as light, temperature, water, atmospheric gases, wind as well as soil (edaphic) and physiographic (nature of land surface) factors.\nThese factors could be said to be the definitions for the exact environmental conditions in which plants need to grow.\nOxygen, carbon dioxide, and nitrogen are the most commonly described gasses; and the wind, soil, and physiographic conditions can also combine in multiple ways to affect organisms.\nIn general terms an ecological system can be thought of as an assemblage of organisms (plant, animal and other living organisms—also referred to as a biotic community or biocoenosis) living together with their environment (or biotope), functioning as a loose unit. That is, a dynamic and complex whole, interacting as an "ecological unit."\n\n\nOther population ecologists, stochastists, (den Boer & Reddingius, 1996), view an ecosystem as an expression of stochastic events, and corresponding responses from organisms. Thus, ecosystems result from the sums of infinite individual responses of organisms to stimuli from non-living and living elements in the environment. The presence or absence of populations merely depends on reproductive and dispersal success and population levels fluctuate in response to stochastic (chance) events. As the number of species in an ecosystem is higher, the number of stimuli is also higher.\n\nCheck the link for more info you need. I'm not familiar with this, besides basic info but hopefully this helps.

Not a very specific question, but usually when we talk in terms of models we want to be able to represent a certain system on a smaller scale. Are you talking about predator-prey relationships, breeding rates and probabilities, what?\n\nOr how a fishery might impact the local ecosystem?\n\nI don't think there is a "Environmental Modeling for Fisheries for Dummies" book!
