Question 15 • SC332 Environmental Science B

Which of the following scenarios is representative of how agricultural practices can affect the environment?

Answer
A
increased oxygen levels in a pond due to fertilizer runoff
B
sediment accumulation in a body of water near a farm
C
soil compaction caused by tillage
D
increased plant growth caused by the application of herbicides

Explanation

Farm activities can loosen or expose soil, allowing rain to carry sediment into nearby streams, lakes, or ponds. The sediment can accumulate in the water and harm aquatic habitats, so “sediment accumulation in a body of water near a farm” is the representative effect. Fertilizer runoff typically contributes to excess algal growth and lower oxygen levels, not increased oxygen levels.
