Read the passage.Flooding occurring along the shoreline of a river is very eroding to the surrounding land. This erosion ends up in the river, causing the river to run muddy. The muddy water decreases the amount of sunlight reaching the aquatic plants, which require sunlight to survive. These aquatic plants provide both a habitat and a food source for fish and other animals that live in the river.
Answer
A
Muddy waters have no oxygen and directly kill the fish.
B
Muddy waters increase habitats for fish to thrive and increase population.
C
Muddy waters will kill aquatic plants, which provide food for fish.
D
Muddy waters hide the fish from fishermen so that won’t be caught.
Explanation
The passage explains that muddy water blocks sunlight from reaching aquatic plants, which need sunlight to survive. If the plants die, fish lose a source of food and habitat. Therefore, the best choice is “Muddy waters will kill aquatic plants, which provide food for fish.”
