​What type of nutrition is observed in mushrooms?​

Correct option is B

The correct answer is (B) Saprotrophic.

• Saprotrophic: As their main source of nutrition, saprophytes are organisms that devour dead or rotting organic matter. Mushrooms use the saprophytic mode of nutrition.
• For this reason, organisms like mushrooms can obtain nutrients from dead and decomposing plant or animal tissue.
• A few examples of saprophytes are fungi, mushrooms, yeast, and many bacterial species. Saprotrophs often have white skin, no leaves, and colorful blooms.

Incorrect options explanation:

• ChemotrophicNutrition: An organism is said to be a chemotroph if it uses the environment's electron donors to oxidize them for energy. They can be either organic (chemoorganotrophs) or inorganic substances (chemolithotrophs). In contrast to phototrophs, which use photons, chemotrophs employ chemicals. Example: They consist of sulfur oxidizers, methanogens, halophiles, nitrifiers, thermoacidophiles, etc.
• Symbiotic Nutrition: It describes the relationship between two creatures where they cooperate to benefit each other by sharing food and shelter. Commensalism is a type of symbiotic relationship in which one organism benefits without the other being harmed. Example: The interaction between nitrogen-fixing bacteria and leguminous plants like clover, alfalfa, and soybeans is an illustration of symbiosis.
• Autotrophic Nutrition: When a creature uses simple inorganic ingredients like water, mineral salts, and carbon dioxide in the presence of sunshine, this process is known as autotrophic nourishment. "Autotrophic" is a phrase made up of the terms "auto," which means "self," and "trophic," which means nutrition. Example: Autotrophs include algae, plants, certain bacteria, and fungi.
