Select the incorrectly matched pair.

Options

A. Fig and fig wasp - Mutualism
B. Cuscuta and hedge plant - Commensalism
C. Cuckoo and crow - Brood parastism
D. Goats and Abingdon tortoise on Galapagos Islands - Competition

Answer

To solve the question of selecting the incorrectly matched pair, we will analyze each option provided in the question step by step.

### Step-by-Step Solution:

1. **Analyze the first option: Fig and Fig Wasp (Mutualism)**
- The fig tree and the fig wasp have a mutualistic relationship.
- The fig tree relies on the fig wasp for pollination and seed development, while the fig wasp uses the fig as a place to reproduce.
- **Conclusion:** This pair is correctly matched.

2. **Analyze the second option: Cascata and Hedge Plant (Commensalism)**
- Cascata is a parasitic plant that grows on hedge plants.
- It derives nutrients from the hedge plant, having lost its chlorophyll and leaves.
- This relationship is not commensalism; it is a form of parasitism.
- **Conclusion:** This pair is incorrectly matched.

3. **Analyze the third option: Cuckoo and Crow (Brood Parasitism)**
- The cuckoo lays its eggs in the nests of crows, which then raise the cuckoo's young.
- This behavior is a classic example of brood parasitism, where one species relies on another for the care of its offspring.
- **Conclusion:** This pair is correctly matched.

4. **Analyze the fourth option: Goats and Abingdon Tortoise (Competition)**
- The introduction of goats on the Galapagos Islands led to the extinction of the Abingdon tortoise due to competition for food.
- The goats had a greater browsing efficiency, which resulted in the tortoise being unable to find enough food.
- This situation exemplifies competitive exclusion.
- **Conclusion:** This pair is correctly matched.

### Final Answer:
The incorrectly matched pair is **Cascata and Hedge Plant (Commensalism)**.
