This scientific law is called as Law of conservation of energy.
Sun is the primary source of energy .Energy once produced by the sun is then utilized by the organisms at various tropic levels. The energy is transferred from one organism to another. Energy is neither created nor destroyed. This is called as law of conservation of energy. Plants uses sunlight and make food and the energy is then transferred to organisms eating it. When the organism dies the energy is released into the environment. This cycle continues and the the law of conservation of energy is maintained.

Explanation;
-A scanning electron microscope (SEM) scans a focused electron beam over a surface to create an image. It useful for studying details of a specimen's surface.
-An electron beam passes over the specimen's surface and displaces electrons, which are then focused on a screen to form an image. Uses a conductive material (gold metal) on the specimen.
-The scanning electron microscope gives much higher clarity of a specimen being viewed than the light microscope can; therefore, internal structures of cells, such as organelles, DNA can be viewed in much more detail. Bacteria and viruses can also be viewed in details and studied under a scanning electron microscope.
