Question

Quizplus · Accepted Answer

Bulldozing the creek banks and disturbing the creek bed will increase the turbidity of the water, making it cloudy. The higher levels of clay and humus in the water are likely to reduce the amount of light that penetrates the water, making it difficult for plants to grow. The reduced light penetration and increased turbidity can also reduce the oxygen level in the creek and lead to a decrease in fish populations. Therefore, the most likely outcome is fewer plants, fewer fish, and cloudy water.
