The correct answer is A. Holozoic.
Holozoic nutrition is a type of heterotrophic nutrition in which organisms ingest particulate food and digest it internally. This is the most common type of nutrition found in animals.
Holozoic organisms have a digestive system that includes a mouth, an esophagus, a stomach, and an intestine. The mouth is used to ingest food, the esophagus is used to transport food to the stomach, the stomach is used to break down food mechanically and chemically, and the intestine is used to absorb nutrients from food.
Holozoic organisms can be divided into two groups: herbivores and carnivores. Herbivores eat plants, while carnivores eat animals. Omnivores eat both plants and animals.
Holozoic nutrition is an efficient way to obtain nutrients. However, it requires a lot of energy to ingest, digest, and absorb food.
Here is a brief explanation of each option:
- Holophytic nutrition is a type of autotrophic nutrition in which organisms use sunlight to produce their own food. This is the most common type of nutrition found in plants.
- Saprophytic nutrition is a type of heterotrophic nutrition in which organisms obtain nutrients from dead or decaying organic matter. This is the most common type of nutrition found in fungi.
- Parasitic nutrition is a type of heterotrophic nutrition in which organisms obtain nutrients from a living host organism. This is the most common type of nutrition found in parasites.
