Which mode of nutrition involves obtaining nutrients from dead and decaying organic matter?

Saprophytic nutrition is a type of nutrition in which organisms obtain nutrients from dead and decaying organic matter. These organisms are called saprophytes. Yeast is an example of an organism that uses saprophytic nutrition.

In parasitic nutrition, the organism lives inside or outside the body of another organism and feeds on its host.

Autotrophic nutrition is the mode of nutrition in which organisms make their own food through processes like photosynthesis.

Holozoic nutrition is a type of heterotrophic nutrition that is characterized by the internalization (ingestion) and internal processing of liquids or solid food particles, such as in animals that eat other organisms.
