The organisms at the bottom level provide energy directly to organisms in all other levels. The Characteristics of Model Organisms. B It lends itself to many studies that are useful to beginning students.

Ever since Mendel identified the basic laws of inheritance using the pea plant scientists have conducted genetic experiments using model organisms. Which of the following best describes the organism located at point B. These organisms are used because they usually are easy to breed and maintain and because they share some similarities with humans in the biological process being studied.

Model organisms can be plants microbes eg yeast or animals eg flies fish worms and rodents all of which are widely studied and have a genetic makeup that is relatively well-documented and well-understood by scientists.
