Cuscuta is

Options

A. Parasitic plant
B. Symbiotic plant
C. Predator
D. Decomposer

Answer

**Step-by-Step Solution:**

1. **Understanding Cuscuta**: Cuscuta, commonly known as dodder, is a genus of twining, leafless plants that are known for their parasitic nature. They do not have chlorophyll and cannot perform photosynthesis.

2. **Identifying the Relationship**: Cuscuta attaches itself to other plants (hosts) and derives nutrients from them. This relationship is known as parasitism, where one organism (the parasite) benefits at the expense of another (the host).

3. **Classifying Cuscuta**: Since Cuscuta lives on the surface of other plants and extracts nutrients, it is classified as an ectoparasite. Ectoparasites live on the outside of their host, while endoparasites live inside.

4. **Excluding Other Options**:
- **Symbiotic**: Symbiotic relationships are mutualistic, where both organisms benefit. Cuscuta does not fit this definition as it harms the host.
- **Predator**: Predators hunt and kill other organisms for food. Cuscuta does not kill its host; instead, it relies on it for sustenance.
- **Decomposer**: Decomposers break down dead organic matter. Cuscuta does not perform this function.

5. **Conclusion**: Based on the above points, Cuscuta is best classified as a parasitic plant.

**Final Answer**: Cuscuta is a parasitic plant.
