1. Types of nutrition of microorganisms:autotrophs heterotrophs prototrophs, auxotrophs. The mechanisms of nutrition are passive diffusion facilitated diffusion,and active transport.

The correct answer is: Autotrophs, Heterotrophs, Prototrophs, Auxotrophs.Autotrophs are microorganisms that can produce their own food from inorganic substances using light or chemical energy. Heterotrophs, on the other hand, obtain their nutrients by consuming organic substances. Prototrophs are microorganisms that can synthesize all the compounds they require from simple raw materials, while auxs are microorganisms that require specific additional growth factors or nutrients that they cannot synthesize themselves.The mechanism of nutrition in microorganisms can be passive diffusion, facilitated diffusion, or active transport. Passive diffusion is the movement of substances from an area of higher concentration to an area of lower concentration without the use of energy. Facilitated diffusion is the movement of substances from an area of higher concentration to an area of lower concentration with the help of specific carrier proteins. Active transport is the movement of substances from an area of lower concentration to an area of higher concentration with the use of energy.
