Explanation:
The organisms in a pond and the physical factors <span>influencing them best describe "an ecosystem" since this is a self-contained environment will multiple organisms. </span>
<span>The question makes it seem that you looked through both types of microscopes at specific samples? As for how they would differ, a light microscope's level of magnification is limited by the physical characteristics of light and therefore can only see objects as small as organelles inside of a cell. A scanning electron microscope, however, does not use light, it uses a beam of electrons to visualize the sample. Electrons are much smaller than the light beam and are able to image much smaller objects, such as molecules and atoms.</span>
