The mode of nutrition in Ascaris is A. Holozoic.
The mode of nutrition refers to how an organism obtains its food. To determine the mode of nutrition of Ascaris, we need to understand how this organism feeds.
Ascaris is a type of roundworm found in the intestines of animals, including humans. It is a parasite, which means it lives inside another organism and obtains its nutrients from the host.
Ascaris feeds by attaching itself to the wall of the host's intestines and absorbing nutrients through its specialized mouthparts. It obtains its food by digesting the partially digested food of the host, taking in nutrients such as sugars, proteins, and fats.
Based on this information, we can conclude that the mode of nutrition in Ascaris is B. Holophytic. This term refers to an organism that obtains its nutrition by directly ingesting complex organic matter.
Therefore, the correct answer is not provided in the options given.
