Question 16 • Environmental Science Q3

How are littoral and riparian zones different?

Answer

A

Littoral zones contain vegetation, while riparian zones do not.

B

Littoral zones have greater access to sunlight than riparian zones.

C

Riparian zones are more important to aquatic animals than littoral zones.

D

Riparian zones occur where water meets land, while littoral zones occur at depths of less than 15 feet.

Explanation

A riparian zone is the land along the edge of a river, lake, or other body of water. A littoral zone is the shallow part of a body of water near the shore, where sunlight can reach the bottom; it is often described as extending to about 15 feet deep. So choice D correctly distinguishes the two zones.
