Scientists select model organisms to understand that particular life form, and its interactions with other life forms and with the environment. They choose particular organisms as models, because of the hopefully wider applicability of the scientific findings. Scientists think that what they learn from the particular model organism will help them understand other organisms. The basic idea comes from Charles Darwin's On the origin of Species, and The descent of man. According to that idea, all living organisms track back to the same ancestor, or the same ancestral gene pool. In particular, model organisms are selected, to understand human disease. Often, it is considered unethical to use people to sort out possible causes of and treatments for disease. So, for example, causes of and treatments for cancer have been studied through the use of mice in laboratories.

A mold is a fossil created by the encasement of an organism in rock, where the organism decays away after solidification of the encasing structure, leaving behind an impression of the original organism. An additional stage is a cast, where the mold is back filled by sedements to create a solid model of the original organism.
Occurs when a new organism is formed from the same organism
The flow chart below indicates the hierarchical levels of the Linnaean classification system. Organism A, Organism B, and Organism C are all classified within the Phylum Chordata. Organism A and Organism B can be further classified into Class Mammalia. Organism C, on the other hand, can be further classified into Class Aves. Which of the following is most likely true about the organisms discussed in the paragraph above? A. Organism A, Organism B, and Organism C all have the exact same structural and behavioral characteristics. B. Organism A, Organism B, and Organism C do not share any structural characteristics with one another. C. Organism B and Organism C share more behavioral characteristics with one another than they do with Organism A. D. Organism A and Organism B share more structural characteristics with one another
Bacteria are unicellular. The cells of the organism they infect are, quite often, part of a multicellular organism.
Orange is the fruit, and yes it is also an organism.

Physical model.:)
A model organism is a species studied fervently by scientists in the hopes of the results being able to be carried over to other organisms. For instance, rats are studied and experimented on, with the results carrying over to humans.

One that used prokaryotes would be the best type of model for the bacterium

Besides humans, some look at primates that are closer to human DNA.
Fruitfly, scientifc name Drosophila melanogaster (dew-loving black-belly), is a model organism used in biological studies. Since they are small, easy to reproduce, has a decoded genome and has many mutant strains, it is most oftenly used in genetics and molecular biology studies involving a model multicellular eukaryotic organism. Other model organisms include Arabidopsis thaliana, a model multicellular plant, zebrafish, a model fish, rats and mice, model mammals, Escherichia coli, a model bacteria, saccharomyces cerevisiae (yeast), a model unicellular eukaryote, and T4 phage, a model virus.

a food web... don't worry i checked my science book... :)
