Question

what is the mode of nutrition. in fungi

Answer 1

The mode of nutrition is fungi heterotrophic.  

They cannot synthesize their own food and are dependent on other ‘organisms’ for their carbon source. They perform extracellular digestion by releasing enzymes into their environment and obtain organic and inorganic nutrients through absorption.  

There are three main ways of obtaining nutrition:  

(i) Saprotrophic: decomposition of ‘dead organic matter’.  

(ii) Parasitic: feeding from a living host.

(iii) Mutualism: living in a mutually beneficial interaction with another organism. (Example: lichen is a mutualism between fungi and algae).

Answer 2

Answer:

Fungi show a symbiotic, saprophytic, and parasitic mode of nutrition.

Explanation:

• Fungi are eukaryotic heterotrophic organisms that get their nutrition from outside sources.
• Fungi get their nourishment by taking organic molecules from their surroundings, such as non-living organic matter, which is mainly dead and decaying stuff.
• The majority of fungi live free in soil or water, but some have parasitic or symbiotic interactions with plants or animals.
• Because fungi are unable to produce their own food, they must rely on other creatures. They're either parasites or saprophytes.
• Saprophytes are fungi that get their nourishment from decaying organic materials.
• Digestive enzymes are produced by fungi, which aid in the breakdown of complex meals into simpler forms.
• Thus, fungi feed on such a basic source of nourishment. This is known as the saprophytic mode of nourishment.
• Saprophytic fungi play an important role in nature's carbon and mineral cycles, as well as the degradation of cellulose and lignin in dead plants. As a result, they help to clean up nature's "trash."
• Parasites are creatures that rely on live plants and animals for their existence.
• An ectoparasite is a fungus that lives on the host's surface
• Endoparasite refers to a fungus that lives inside an organism.
• Fungal parasites contain haustoria, which are specialized absorbing structures that arise as hyphal outgrowths and absorb food material from the host.
• They can also exist as symbionts, forming lichens and mycorrhizae in conjunction with algae and higher plants' roots.
