Question

Housefly shows which type of nutrition from the following?

• A. Saprozoic
• B. Parasitic
• C. Holozoic
• D. Symbiotic

Answer 1

The correct option is A Saprozoic

• In saprozoic nutrition, the organism secretes the digestive enzyme on their food and then intake the partially digested food. Examples of organisms showing the saprozoic mode of nutrition are spiders, houseflies, and starfish.
• In the parasitic mode of nutrition, the organism is completely dependent on its host. They uptake fully digested food from their host. Example: protozoans.
• The holozoic mode of nutrition involves digestion and absorption occur in the following order: ingestion (uptake of food from the mouth), digestion, absorption, assimilation, and egestion. Example: mammals.
• In the symbiotic relationship, two organisms divide their work. For example, the lichen shows the symbiotic relationship between algae and fungi. The fungi absorb minerals and water from the surroundings while the algae prepare the food by photosynthesis.

Hence, the correct answer is option (A).
