Quizplus · Accepted Answer

All of these factors contribute to the degradation of freshwater ecosystems. Dams restrict natural river flow, altering the physical and biological characteristics of rivers. Excessive water withdrawal for agriculture reduces the amount of water available for other uses and can lead to dry rivers and lakes. Destruction of wetlands eliminates important habitat and can disrupt the natural water cycle. Invasive species can outcompete native species, altering the ecological balance of an ecosystem.
