True or False: Variable watermilfoil can overtake deepwater lakes.

The statement that variable watermilfoil can overtake deepwater lakes is false. While variable watermilfoil is an invasive aquatic plant that can thrive in a range of water conditions, its growth is typically more pronounced in shallower areas. This is largely due to the need for adequate sunlight for photosynthesis, which is less available in deeper waters. In deep lakes, the light penetration diminishes, limiting the ability of variable watermilfoil to establish and proliferate in those depths.

In contrast, shallow areas tend to provide the optimal environment for its growth, leading to dense populations that can outcompete native plant species and disrupt local ecosystems. Thus, while it can spread in various water bodies, it is unlikely to dominate deepwater lakes, making the statement false.
