Housefly shows following type of nutrition

Options

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

Answer

**Step-by-Step Solution:**

1. **Understanding Nutrition Types:**
- Begin by understanding the different types of nutrition: saprophytic, parasitic, holozoic, and symbiotic.

2. **Analyzing Saprophytic Nutrition:**
- Saprophytic (or saprozoic) nutrition involves feeding on dead and decaying organic matter. Organisms secrete enzymes to break down the food externally before absorbing it.
- Houseflies do not exhibit this type of nutrition as they do not primarily feed on dead matter in this manner.

3. **Evaluating Parasitic Nutrition:**
- Parasitic nutrition involves one organism living off another, often harming the host. Houseflies are not parasites; they do not live off another organism in this way, although they can act as vectors for diseases.

4. **Identifying Holozoic Nutrition:**
- Holozoic nutrition is characterized by the ingestion of solid food particles, which are then digested internally with the help of enzymes.
- Houseflies feed on liquid food by regurgitating digestive enzymes onto it, which allows them to absorb the nutrients. This aligns with holozoic nutrition.

5. **Considering Symbiotic Nutrition:**
- Symbiotic nutrition refers to a mutually beneficial relationship between two organisms. Houseflies do not have such relationships, making this option incorrect.

6. **Conclusion:**
- Based on the analysis, the type of nutrition exhibited by houseflies is holozoic nutrition. Therefore, the correct answer is option 3.

**Final Answer:**
Housefly shows holozoic nutrition.
