Which of the following species is susceptible to drawdown?

Large-leaf Pondweed is indeed a species that is susceptible to drawdown. The term "drawdown" refers to the process of lowering water levels in a body of water, which can stress or expose aquatic plants to conditions that may lead to their decline or death. Large-leaf Pondweed, being an aquatic plant that relies on consistently submerged conditions, can be adversely affected when water levels drop. This is because its growth and reproduction are supported by water coverage, and reduced water levels can limit its access to the nutrients and habitat it requires for survival.

In contrast, species such as Cattail and Water Lily are more resilient to fluctuations in water levels due to their adaptive characteristics. Cattails can withstand periods of drier conditions as they often grow in wetlands that experience seasonal changes in water. Similarly, Water Lilies are equipped to manage varying water depths and can thrive even when water levels drop seasonally. Duckweed, while it does float on the surface of the water, can also tolerate some changes in water level but does not exhibit the same sensitivity as Large-leaf Pondweed. Therefore, Large-leaf Pondweed is the best representation of a species that is specifically susceptible to drawdown conditions.
