____is an example for a parasite.

Options

A. Tiger
B. Cuscuta
C. Fungus
D. Pitcher plant

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for an example of a parasite. A parasite is an organism that lives on or in a host organism and gets its food at the expense of its host.

2. **Analyzing the Options**: We have four options to consider:
- A) Tiger
- B) Cascata
- C) Fungus
- D) Pitcher plant

3. **Evaluating Each Option**:
- **Tiger**: A tiger is a carnivorous animal that hunts and eats other animals. It is not a parasite because it does not live on or in another organism to obtain its food.
- **Cascata**: This is a type of parasitic plant. It attaches itself to a host plant and derives nutrients from it, making it a true example of a parasite.
- **Fungus**: Fungi typically decompose dead organic matter (saprophytes) and do not derive their nutrients from living hosts, so it is not classified as a parasite.
- **Pitcher Plant**: This plant captures and digests insects for nutrients, but it is not a parasite since it does not rely on a living host for its sustenance.

4. **Conclusion**: Based on the analysis, the only organism from the options that qualifies as a parasite is **Cascata**.

5. **Final Answer**: The correct answer is **Cascata**.
