find the odd one w.r.t. parasitism

Options

A. Cuscuta
B. Liver fluke
C. Female mosquito
D. Plasmodium

Answer

To find the odd one out with respect to parasitism, we need to analyze the given options: Cascata, River flow, Female mosquito, and Plasmodium.

**Step 1: Understand Parasitism**
- Parasitism is a type of symbiotic relationship where one organism (the parasite) benefits at the expense of another organism (the host). The parasite obtains food and shelter from the host, which can be either inside or outside the host's body.

**Step 2: Analyze Each Option**
1. **Cascata**: This is a plant parasite that derives nutrients from its host plant.
2. **River flow**: This is not a living organism and does not engage in parasitism.
3. **Female mosquito**: This is an animal parasite that feeds on the blood of its host (typically mammals).
4. **Plasmodium**: This is a protozoan parasite that causes malaria in humans, also an animal parasite.

**Step 3: Identify the Odd One Out**
- Among the options, Cascata is a plant parasite, while the Female mosquito and Plasmodium are animal parasites. The River flow does not fit into the category of organisms at all.

**Step 4: Conclusion**
- The odd one out with respect to parasitism is **Cascata**, as it is the only plant parasite among the options provided.
