Question

A) Saprozoic nutrition
B) Parasitic nutrition
C) Saprophytic nutrition
D) Holozoic nutrition

Answer 1

Hint: Nutrition is the process of obtaining food and then using it for obtaining energy, growth and repair of the body. Heterotrophic nutrition is described as the ingestion and internal processing of gaseous, liquid or solid food particles.

Complete Answer:
- Saprotrophic nutrition is that sustenance wherein a creature acquires its food from rotting natural matter of dead plants, dead creatures and spoiled bread, and so on. The creatures having a saprotrophic method of sustenance are called saprophytes like Fungi ( bread molds, mushrooms), and numerous microscopic organisms.
- Parasitic nutrition is that sustenance where a living being gets its food from the body of another living creature without slaughtering it. A parasite is a living being (plant or creature) which feeds on another living being called its host. Few examples are Plasmodium and roundworms.
- Holozoic nutrition is that sustenance where a creature takes the food materials into its body by ingestion, the ingested food is processed and afterward consumed into the body cells of the living being as in Humans.
- Saprozoic nutrition is the type of nutrition in which organic nutrients are taken up in dissolved form; normally refers to animals or animal-like organisms.

So, the correct answer is option D.

Note: Nutrition in which the entire organism engulfs the food it plans on eating up. The mode of nutrition is known as holozoic nutrition. It involves the ingestion, digestion and egestion of food material.
