The usual example is that of a pond; a self-contained ecosystem.\nNow you need to do your learning and consider how the organisms depend upon one another.

The Chicken - \n\nWhen God created the animals he gave them the ability to go out and mulitply of their own kind.  He didn't just make eggs - he made the actual animal.

No one can create or help in creating living things.\n\nPlanting is not creating, because you are planting seeds of an already created mother plant.\n\nGiving birth is not creating, because you are delivering someone who God has created in your womb.\n\nCreation of living things is an adjective which is exclusive for GOD ... \n\nGod has created mosquitos ... can anyone create a living mosquito ??? How tiny it is but no one can create a single living mosquito .... but GOD

Trees are phototrophs, they produce their own food by using carbon dioxide, water, and sunlight.

It is a characteristic of the organism, made by nature.

right! plants have the ability to produce their own food. They get essential nutrients from the sun's rays and from the soil. When plants get certain elements and/or nutrients from its major surroundings, it is therefore able to convert the nutrients into food; making the plant survive with no dependence from us.

Your question has a number of difficult aspects to it, but I have asked a friend of mine to help me do some research into the answer for you and I think he has included a great number of pieces of information that you may find interesting.\nHere is what I eventually decided was the most productive answer to give you. I hope it helps you out! (after all, it is 99% his answer I have included below. He generally gives me such good feedback that I try to quote him directly as much as possible.)\nHere we go: An animal is:\nAn organized living being endowed with sensation and the power of voluntary motion, and also characterized by taking its food into an internal cavity or stomach for digestion; by giving carbonic acid to the air and taking oxygen in the process of respiration; and by increasing in motive power or active aggressive force with progress to maturity.\nOR:\nAny of a kingdom (Animalia) of living things including many-celled organisms and often many of the single-celled ones (as protozoans) that typically differ from plants in having cells without cellulose walls, in lacking chlorophyll and the capacity for photosynthesis, in requiring more complex food materials (as proteins), in being organized to a greater degree of complexity, and in having the capacity for spontaneous movement and rapid motor responses to stimulation" These are the animal subkingdoms, and the principal classes under them:\n* Vertebrata, including Mammalia or Mammals, Aves or Birds, Reptilia, Amphibia, Pisces or Fishes, Marsipobranchiata (Craniota); and Leptocardia (Acrania).\n* Tunicata, including the Thaliacea, and Ascidioidea or Ascidians.\n* Articulata or Annulosa, including Insecta, Myriapoda, Malacapoda, Arachnida, Pycnogonida, Merostomata, Crustacea (Arthropoda); and Annelida, Gehyrea (Anarthropoda).\n* Helminthes or Vermes, including Rotifera, Ch�tognatha, Nematoidea, Acanthocephala, Nemertina, Turbellaria, Trematoda, Cestoidea, Mesozea.\n* Molluscoidea, including Brachiopoda and Bryozoa.\n* Mollusca, including Cephalopoda, Gastropoda, Pteropoda, Scaphopoda, Lamellibranchiata or Acephala.\n* Echinodermata, including Holothurioidea, Echinoidea, Asterioidea, Ophiuroidea, and Crinoidea.\n* Coelenterata, including Anthozoa or Polyps, Ctenophora, and Hydrozoa or Acalephs.\n* Spongiozoa or Porifera, including the sponges.\n* Protozoa, including Infusoria and Rhizopoda.

Living things use, store, and emit energies and other chemical compounds; non-living things don't.  Living organsims burn off 90% of all the energy that it intakes and only 10% turns into other muscle tissue or is stored for further usage.  So if a bird eats ten fish then only abou 1 of those fish's nutrients will make up the bird's mass and be stored the other 9 fish's nutrients will be burned in daily activities.  At least I'm pretty sure that's how it is.

We can think in general terms of a food chain consisting of three main groupings, or trophic levels: plants, herbivores, and carnivores. Plants are at the "bottom" of the food chain—they are able to make their own food by using the energy from the sun (they are autotrophic). Because they produce their own food, they are called Producers. All other living things that can't make their own food must consumer the producers, so they are called consumers (and are heterotrophic). Consumers are higher up the food chain (at a higher trophic level) and are either herbivores (they directly consume the producers) or carnivores (they eat other consumers). Macroinvertebrates are heterotrophic and may be both herbivores and carnivores. \n\nBecause benthic macroinvertebrates eat and are eaten, they are smack-dab in the middle of the food chain, a position that is critical in a healthy stream ecosystem. Herbivorous stream bugs consume plants and algae (these bugs are the scrapers and shredders). \n\nThe benthic macroinvertebrates that eat small fish, small amphibians, and other stream bugs are the carnivores. These predaceous macroinvertebrates are the predators\n\nTo confuse matters slightly, there is another group in addition to the herbivores and carnnivores. Detritivores are sort of a combination of herbivores and carnivores. Detritivores shred and eat leaves and other organic matter that contain nourishing fungi, algae, and bacteria. They absorb the nutrients as they break down the material into smaller sizes that other bugs utilize. Detritivores are the shredders and collectors. \n\nStream bugs may get eaten by other macroinvertebrates and fish that depend upon them for food. For example, both juvenile and adult salmon eat macroinvertebrates. And not only do other consumers need them for food, but when the bugs die, they decay and leave nutrients behind that flow back into the food chain. \n\nSo without the stream bugs, organic materials won't be processed, nutrients won't get recycled back into the system, and many consumers won't have any food—in short, the system degrades until it is unhealthy or dead, then most bugs couldn't live there even if they wanted to.

Usually, textbooks define living things as anything that has a list of characteristics.  For example, they reproduce, they metabolize, they grow, they respond to their environment....\n\nTHere isn't a single thing that you can use to define "living".

Organisms resembling the mitochondria in cells today. That is the simple reason why all living things have them and why they (mitochondria) have their own nucleic acids.

Plants store food as starch, sugar, glucose, and sometimes protien (as in pulses). And that is what we eat as fruits etc.

protozoa are single cellular organisms thus they do not possess systems they have cell organells to perform different functions . in protozoa food is circulated with the help of vacuole

...to live and reproduce? You need to be more specific... what kind of animal cell? In what organ? Or is it a single-celled organism? Do you mean the structure?
