Answer 2

Answer:

Mushroom (which are basically members of Kingdom Fungi) is an example of a saprotroph.

Explanation:

Types/Modes of Nutrition:

The plants (except the fungi) are the sole organisms that are capable of synthesizing their own food (organic matter) by harnessing solar energy and nutrients from the soil and atmosphere.
Such types of organisms are classified as autotrophs and the mode of nutrition is known as autotrophic nutrition.

Rest all other organisms that derive their nutrition directly or indirectly from the autotrophs are known as heterotrophs.

The heterotrophs are further divided into the following sub-categories:

1. Saprophytic: These are the organisms that obtain nutrition from dead or decaying organic matter. E.g., Yeast, Fungi, etc.
2. Parasitic: These are the organisms that get attached to another organism and obtain/suck nutritious fluid from it. The organism that it gets attached to is known as the host. The organism does not 'kill' the host but often makes it weak. E.g., Cuscuta, Plasmodium, etc.
3. Holozoic: These are the organisms that engulf (ingest) organic matter (parts of other plants/animals) and digest that organic matter to obtain energy from it. The undigested materials are at least egested out of the body of the organism. E.g., Amoeba, Man, etc.
