A microscope is an instrument which is used to see the objects which are tiny and difficult to observe through naked eye. The microscope magnifies these objects and enlarge their size. It has two lenses that are ocular and objective.
The magnification for 10X ocular lens and the 40X objective lens is expected to produce the total magnification of 400X (10 x 40 = 400).
The relationship between the food we eat and the energy in our bodies is that food is converted to energy and without food we will not have energy, I think hopes this helped you out a little.
