Magnification is a term used to describe the degree to which an object appears larger under a microscope. The level of magnification is determined by the eyepiece and objective lens used in a microscope. The eyepiece typically comes with a magnification level of 10x, meaning that objects will appear 10 times larger than their original size. The objective lens, on the other hand, determines the overall magnification of a microscope.

When it comes to viewing living organisms, it is important to have a microscope with high magnification capabilities. This is because living organisms are often small in size and require a powerful lens to observe them effectively. There are different types of microscopes available for observing living organisms, including compound microscopes and stereo microscopes.

Compound microscopes are the most commonly used type of microscope for observing living organisms. They have multiple objective lenses that can magnify specimens up to 1000x. This makes them ideal for viewing cells and other small organisms. Stereo microscopes are also used when observing live organisms. They provide a lower magnification level than compound microscopes but have the advantage of producing a 3D image of the specimen being observed.

In conclusion, when it comes to observing living organisms under a microscope, it is important to choose a microscope that has high magnification capabilities. Compound microscopes and stereo microscopes are the most commonly used options for this purpose. The level of magnification needed will vary depending on the size of the specimen being observed, but in general, higher magnification will provide a more detailed view of the organism.
