What effect, it any, would the extinction of a mutualistic pollinator have on the plant it pollinates ?

Options

A. No effect
B. Decreased pollination
C. No effect because substitute pollinator is available
D. The plant would not be pollinated.

Answer

### Step-by-Step Solution:

1. **Understanding Mutualism**: Begin by defining mutualism. Mutualism is a symbiotic relationship where both species involved benefit from the interaction. In this case, the mutualistic relationship is between a pollinator (like bees or butterflies) and a plant.

2. **Role of Pollinators**: Explain the role of pollinators in the life cycle of plants. Pollinators are essential for the transfer of pollen from one flower to another, which is necessary for fertilization and subsequent fruit and seed production.

3. **Consequences of Extinction**: Consider the implications of the extinction of a mutualistic pollinator. If a specific pollinator goes extinct, the plant that relies exclusively on that pollinator for its reproduction will face challenges.

4. **Impact on Pollination**: Analyze the direct impact on pollination. Without the mutualistic pollinator, the plant would not receive the necessary pollen transfer, leading to a decrease in successful fertilization.

5. **Conclusion**: Based on the analysis, conclude that the extinction of a mutualistic pollinator would result in the plant not being pollinated. Thus, the correct answer to the question is option D: "The plant would not be pollinated."
