Hookworm feeds on

Options

A. Semidigested food
B. Undigested food
C. Digested food
D. Mucous membrane and blood

Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question asks about the feeding habits of hookworms, which are parasitic nematodes.

2. **Understand the Host**: Hookworms primarily infect humans as their host. They attach themselves to the host's intestinal wall.

3. **Feeding Mechanism**: Adult hookworms are known to feed on the host's blood. They do this by attaching to the mucosal membrane of the small intestine.

4. **Eliminate Incorrect Options**: The options provided include:
- Semi-digested food
- Undigested food
- Digestive food
- Mucus
- Membrane
- Blood

Since hookworms do not feed on food (whether semi-digested, undigested, or digested), we can eliminate those options.

5. **Correct Answer**: The correct answer is that hookworms feed on the mucous membrane and blood of their host.

**Final Answer**: Hookworm feeds on mucous membrane and blood.
