Question

Which of the following has a saprophytic mode of nutrition?
a. Roundworm
b. Leech
c. Mushroom
d. Lice

Answer 1

Hint: The source of nutrition by which non-green plants absorb nutrients from dead and decomposing matter is called saprophytic or saprotrophic nutrition. Fungi, yeast, and several bacteria are examples of saprophytes. A parasite is an organism that lives on or in a host organism and gets its food from or at the cost of its host.

Complete answer:
The nourishment of Mushroom is saprophytic, which is just like heterotrophic nutrition. This is the reason organisms like mushrooms nourish on a dead and decomposing plant or animal matter. Mushrooms prefer shadowy, cool, moist, and wet growing environments. They grow best in temperatures between 55-60 degrees Fahrenheit, faraway from drying, direct heat, and drafts. Roundworms, leeches, and lice are parasites because they survive or in a further organism and obtain their nutrition from them.

There are so many mushroom spawn suppliers, which manufacture the quality based fresh and dried mushroom in the market with the best nutritional value.

Hence, the correct answer is option (C).

Additional information:
There are three major classes of parasites that can cause disease in humans: protozoa, helminths, and ectoparasites.
> Helminths are big, multicellular organisms that are commonly visible to the uncovered eye in their adult stages. Like protozoa, helminths can also be either free-living or parasitic.
> Parasitic infections cause a great burden of disease in both the tropics and subtropics as well as in more moderate climates. Of all parasitic diseases, malaria causes the most deaths worldwide. Malaria kills around 660,000 people each year, mainly of the young children in sub-Saharan Africa.

Note: Saprophytes need suitable conditions to grow. In good access to water, they grow well. Under alkaline conditions they do not thrive. The best soil for saprophytic growth is neutral or slightly acidic. Most of the saprophytes do not grow under anaerobic conditions and some amount of oxygen should be present in the soil for their growth.
