Weeds are known for their aggressive growth habits, which is a defining characteristic that allows them to outcompete and control other surviving species in a given environment. These aggressive growth patterns enable weeds to quickly establish themselves, spread rapidly, and often dominate the available resources such as water, nutrients, and light.

This competitive edge makes it challenging for desirable plants to thrive, as the weeds can overtake them and hinder their growth through shading or resource competition. Consequently, many weeds adapt quickly to their surroundings, exhibit resilience against various control methods, and can proliferate under a range of conditions, further enhancing their role in controlling populations of other species.

The other characteristics listed do not universally apply to all weeds. While some may have deep tap roots or reproduce via seeds, these traits vary widely among different weed species. Additionally, not all weeds thrive specifically in urban areas, as many are adapted to rural or agricultural settings. Thus, aggressive growth habits distinctly characterize weeds and their ability to control survivor species.
