Concept:The mode of nutrition is classified by how an organism obtains and processes its food.
Explanation:Holozoic nutrition is the type in which organisms take in solid organic materials into their body.
In this mode, food is ingested first and then digested inside the body.
Most animals, such as humans and amoeba, show holozoic nutrition.
Parasitic nutrition involves taking food from a living host without killing it.
Saprophytic nutrition involves feeding on dead and decaying organic matter.
Symbiotic nutrition involves two organisms living together, often benefitting each other.
So, the intake of solid organic materials is a defining feature of holozoic nutrition.
Answer:The correct answer is B. Holozoic.
