Noxious weeds are weeds that invade ecosystems and grow very quickly and aggressively. In Colorado, more than 1 million acres are affected by noxious weeds. How do noxious weeds affect the biodiversity of an ecosystem? (SC.912.L.17.5) * 1 point The biodiversity increases slightly because they represent another species in the area. They increase the biodiversity because they increase the total energy of the producers. The biodiversity usually decreases greatly as the noxious weeds outcompete the local plants. The biodiversity is not affected at all since the noxious weeds simply replace the dominant plant in the ecosystem.

The correct response is: The biodiversity usually decreases greatly as the noxious weeds outcompete the local plants.
Noxious weeds tend to outcompete native plants for resources such as water, nutrients, and sunlight, leading to a decrease in biodiversity. This reduction in the variety of species can disrupt the balance of the ecosystem and negatively impact other organisms that rely on native plants for food and habitat.
