1. Simple optical microscope. One lens.
Disadvantage: Only Van Leeuwenhoek made them, and he's dead.
Advantage: Worked pretty well. With them, Van Leeuwenhoek discovered protozoa and bacteria.

2. Compound optical microscope. Has both an ocular and objective lens.
Disadvantage: limited resolution. Can resolve bacteria, but not smaller things like viruses.
Advantage: can be used with live specimens (using phase contrast or polarized or other special illumination).

3. Binocular dissecting microscope (optic). Has a pair of ocular and objective lenses, and supposedly presents a "3D" view of the specimen to the viewer (I was never able to see in 3D using these darn things).
Disadvantage: Limited magnification
Advantage: Can be used to perform surgery on small but not microscopic specimens, such as fruit flies. Is used in "microsurgery" in hospitals too.

Hope this helps buddy!

Answer:

The three types of specimens a dissecting microscope are as follows:

  1. Optical Microscopes.
  2. Electron Microscopes.
  3. Scanning Probe Microscopes.
  • Optical microscopes are the oldest and the simplest microscope it uses a single convex lens to enlarges the image placed under its focus.
  • Electron Microscope is used by scientists to study cell, this microscope fire beams of electrons on the subject which is held in the vacuum-sealed tubes.
  • Scanning probe microscopy is a powerful microscope, it can detect matters smaller than the nano-meter however its images have no color because it uses probe measure things other than visible light.

Why is it necessary to have a constant input of energy into an ecosystem?
IrinaK [193]
If there was not a constant Input of energy into the ecosystem then nothing would have the power to do anything and nothing would be alive. the energy starts with the sun, then goes to plants, then animals that eat the plants, and then the animals that eat those animals, Ect. if this chain reaction did not happen then the plants wouldn't have to power to go through photosynthesis and then we would get no energy. the amount of energy lessen with every chain that it goes through, this is why we get more energy eating plants and why they are healthier.
