Amoeba are the consumers that surround, engulf, and ingest their food.
<h3><u>Explanation</u>:</h3>
Amoeba is a unicellular organism that belongs to the kingdom Protista. This organism are having eukaryotic cells without any cell walls. These organisms have each and every cellular organelle that are needed to perform metabolism.
Amoeba are consumer in mode of nutrition. Whenever they senses some food, they push a part of their cytoplasm packed in cell membrane towards the food to cover it. This process is called pseupodia.
This pseupodia engulfs the food and performs phagocytosis or pinocytosis. This food is covered in a cell membrane inside the cytoplasm which is called the food vacoule or endosome. This then fuses with a lysosome to digest and then the excretory product is let off by the secondary vacoule.
The major difference between a light microscope and a electron microscope would be that with the light microscope, a beam of light is used to focus the image. In an electron microscope, a beam of electrons is used to focus the image. Other notable differences would be with the light microscope, your specimens must be very thin; thin enough for light to pass through them. With the EM, you can place whole specimens that can generate 3D images. There is a much more complex specimen preparation process for the EM, where light microscope slide making is fairly simple in comparison. You can view live and wet specimens with a light microscope but you cannot with the EM because an EM requires specimens to be placed in a vacuum chamber. Lastly, the EM is very large and complex to operate, where the light microscope is somewhat portable. Hope this helps!
