Question

how has the removal of wetlands impacted rivers and streams? a. it has increased the rate of absorption, causing a decrease in water levels. b. it has decreased the rate of absorption, causing greater incidents of flooding. c. it has hindered the migration of fish, causing a loss in biodiversity. d. wetland removal has had no measurable impact on rivers and streams. please select the best answer from the choices provided

Explanation:

Wetlands act as natural sponges, absorbing and storing water. When removed, the water - absorption capacity decreases, leading to more frequent and severe flooding as water has less natural storage. Option a is incorrect as removal decreases absorption rate. Option c is wrong as wetland removal has significant impacts. Option d is incorrect as there are measurable impacts. Option b is correct because decreased absorption due to wetland removal can cause flooding and also disrupt fish migration and biodiversity.

Answer:

B. It has decreased the rate of absorption, causing greater incidents of flooding.
