Question

The fungi are
A. Autotrophic
B. Holotropic
C. Chemotrophic
D. Heterotrophic

Answer 1

Hint: Fungi are those organisms which belong to the kingdom Fungi that includes so many other organisms like yeasts, mushrooms, etc. And they are also eukaryotic organisms. Here in the question they are asking about the mode of nutrition of the fungi. So we will explore the options in detail.

Complete answer:
Fungi can be useful to humans as well as it is also harmful for humans. Some species can be used as medication and also helpful in making so many foods like bread, cakes etc. While few species of fungus can cause diseases to humans and it can also destroy the edible.
Let's explore the options one by one:
1. Autotrophic means those organisms which can prepare their own food. So, fungi cannot prepare its own food. Hence, this is an incorrect option.
2. Holotropic is that mode of nutrition in which the organism involves the internal processing of solid food particles are liquids and gaseous materials. Nutrition takes place in several stages like ingestion, digestion, absorption, assimilation and excretion. So, this is also an incorrect option.
3. Chemotropic mode of nutrition refers to obtaining energy from the oxidation of inorganic molecules. So, this is also not the mode of nutrition of fungi.
4. Heterotrophic mode of nutrition refers to the mode in which organisms depend on other organisms for food to survive. The fungi feed on dead or decaying organic matter or completely depend on the host organism.

Therefore, the correct answer is option (d).

Note:
Fungi grow in warm and humid places more. They can be found everywhere like on air, water, soil, animals, plants, etc. They have different names as well, this depends on the area where they grow. Their cell wall is made up of chitin or the fungal cellulose which is a polysaccharide.
