D. animals

Answer

To solve the question regarding the adaptations of a particular species of plant that produces light, non-sticky pollen and has long, feathery stigmas, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Characteristics of Pollen**: The plant produces light and non-sticky pollen grains in large numbers. This indicates that the pollen is adapted for a specific mode of pollination.

2. **Consider the Function of Light and Non-Sticky Pollen**: Light pollen grains can be easily carried by the wind, while non-sticky pollen prevents them from adhering to surfaces during their travel. This suggests that the pollen is designed to be dispersed over a wide area.

3. **Analyze the Stigma Structure**: The stigmas are described as long and feathery. This structure is advantageous for capturing airborne pollen grains effectively. The feathery nature increases the surface area, allowing for better interception of pollen.

4. **Determine the Pollination Method**: Given that the pollen is light and non-sticky, and the stigmas are long and feathery, these adaptations are characteristic of wind pollination, also known as anemophily. This method relies on the wind to transfer pollen from the male parts of the flower to the female parts.

5. **Conclude the Answer**: Therefore, the modifications of light, non-sticky pollen and long, feathery stigmas facilitate pollination by wind (anemophily).

### Final Answer:
The modifications facilitate pollination by wind (anemophily).
