tell me about plants ecosystem  and explain what an aboitic factor is ?
95083
An aboitic facotor is some non-living factor in the envirnoment that the organism cannot control. For a plant tempuratue, sunlight, etc. A plant ecosystem is basically the plant makes the food in photosythesis, gets eaten(others may eat the plant eaters), decomposers break down  dead consumers, and it starts over. Plants are primart producers. The first thing to eat them are primary consumers then secondary consumers get the idea.

writing an essay is my guess\nit really sucks to be u \nand ill just point out that least and most contradict each other\ngood luck on the paper with those grammer skill\nno, i am a nice person\nsomewhere in the shriveled black heart lies some sympathy\nnow back on topic:\n\n1.  ecosystems are balanced, and all species share resources with other species, and are dependent on each other because if one side eats too much, there is less food for the others, adn they die\n\n2.   an ecosystem is everything that life has anything to do with.  So, if say a human pollutes the air, a plant cannot breate, the herbivore cannot eat, adn everybody dies again\n\n3. humans recieved this most wonderful gift of travel, but the rest of the animal world hates us for it now.  what i am saying, since really nothing stops a human from adapting the habitat to fit in.  we are really quite good at fitting in.  so, natural restrictions that normally limit a species from entering, dont even trip us.  We come into hte place and take space away from others, effectively pushing species onto each other, and they compete for the things htey need even if there is not enough, they then adapt and we futher evolution\n\nin the end it is all about resources, and competition (try Darwin)\ni hope my rambling helped

Microorganisms (soil bacteria) are the most important component of any soil. They dissolve rock particles and release nutrients to the plants through decomposition. The microorganisms release carbon dioxide gas into the film of water surrounding soil particles, making the water slightly acid. This causes it to react with the rock particles and dissolve them, providing a slow, steady release of nutrients.\n\nAll microorganisms decompose decayed vegetation or other microorganisms. The decayed vegetation, called humus, is the basis for soil life. Without humus, we get no naturally formed nitrogen, and plants become weak and more susceptible to insect attack. Humus has other beneficial effects besides feeding soil microorganisms. It mechanically loosens the soil itself and creates a texture called good tilth.\n\nWhen soil has good tilth, it is soft, porous and easy to work and crumbles easily into fine pieces. Water penetrates the soil better and the soil also holds more water.\n\nTilth prevents the formation of hard crusts on the soil's surface. It allows plants to put out larger root systems easily. When there is lots of air in the soil, microorganisms flourish and speed mineral release. Good tilth allows delicate seedlings to get a good start. Focusing on the basics: \n\nAbundant Soil Microorganisms \nImproving Humus and Tilth \nis the first step and the foundation for long-lived successful reclamation, and restoration of the soil ecosystem.

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/

Well, some simple abiotic factors would be that giraffer's are affected by the pH of the water they drink, its salinity, body temperature, environmental temperature, as well as air qualities. I could look into the actual environmentalcontext fo the giraffe species and see what it lives around.\n\nfor biotic factors, we could say human encroachment, predation of lions, for instance. We also know that the leaves and grasses it feeds on is another biotic factor. We can look at sexual competition (if there is any) in the giraffe species, and of course any incidences of bacterial disease that a giraffe is significantly prone to.

OH YEAH!  The abiotic things.  Community is the interaction of living species with each other, ecosystem is those interactions Plus interaction with abiotic factors (water, temperature etc).\nLet me make sure.\n\nYep Yep.  i think that's it

A good way to explain a food web is to have students create their own. When I was volunteering with a wildlife rehab center last summer, we did some educational programs at a local camp. Each of the students was given an element that would be in a food web, animals, plants, soil, the sun, etc. Then we would start with one of these, probably the sun is the easiest, and then go from there to show them how each depends on one another.

Plants are a major group of living things including familiar organisms such as trees, flowers, herbs, and ferns. About 350,000 species of plants have been estimated to exist. As of 2004, some 287,655 species had been identified, of which 258,650 are flowering.

In ecology, an ecosystem is a combination of all the living and non-living elements of an area. Ecosystems are the smallest level of organisation in nature that incorporates both living and nonliving factors. They can range in size from as big as the Sahara Desert to as small as a pond. The term microecosystem may be used to describe a very small (often closed) ecosystem.\n\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\nEarly conceptions of this unit showed a structured functional unit in equilibrium of energy and matter flows between its constituent elements. Others considered this vision limited, and preferred to understand an ecosystem in terms of cybernetics. From this view an ecological system is a functional dynamic onganization, or what was also called steady state. Steady state is understood as the phase of an ecological system's evolution when the organisms are "balanced" with each other and their environment. This balance is achieved through various types of interactions, such as predation, parasitism, mutualism, commensalism, competition, and amensalism. Introduction of new elements, whether abiotic or biotic, into an ecosystem tend to have a disruptive effect. In some cases, this can lead to ecological collapse and the death of many native species. The branch of ecology that gave rise to this view has become known as Systems Ecology. The abstract notion of ecological health attempts to measure the robustness and recovery capacity for an ecosystem; that is, how far the ecosystem is away from steady state.\n\nThe size and scale of an ecosystem can vary widely. It may be a whole forest, a community of bacteria and algae in a drop of water, or even the geobiosphere itself. Different ecosystems are often separated by geographical barriers, like deserts, mountains or oceans, or are isolated otherwise, like lakes or rivers. As these borders are almost never rigid, ecosystems tend to blend into each other. As a result, the whole earth can be seen as a single ecosystem, or a lake can be divided into several ecosystems, depending on the scale used.

Universal.\nPlants are producer organisms converting sunlight and minerals into food that we can eat. They absorb carbon out of the atmosphere, produce oxygen and as importantly pump water from the ground into the air, making more water available as rain and preventing salt from building up in the soil surface (salination). Plants prevent soil erosion through slowing the impact of rain and wind. They provide wood for fuel, building and paper, they provide homes and food for myriads of other animals, and without plants we would be in a sorry state of affairs. Plants beautify the landscape and make us feel better about our surroundings. Plants are good things,

You have got some things muddled up here.\n\nGestation and offspring dependency doesn't apply to flowering plants.\nSexual maturity and frequency of reproduction - there are three patterns:\n- annuals - life cycle complete within one year, parent plant dies;\n- biennials - life cycle takes two years - first year plant establishes itself, over-winters, reproduces next year and dies;\n- perennials - live for many years and make seeds every year.\nAs for the number of seeds they make, this is very variable. Some species make only a few, some make lots.\n\nLink 1. - general information.\nLink 2. - a bit more detail.\nLink 3. - a site to help with all the technical words, very useful.

How about you find out what an abiotic factor is? Then you tell us what the answer is, and then we'll tell you why you are right or wrong. How's that sound?\n\nDon't expect other people to do your homework for you, especially when the questions are this simple. It's dishonest and you learn nothing. \n\nYou also get incorrect answers such as the one quirkgirl just gave.
