The zone at the edge of a lake or ocean which is alternatively exposed to air and immersed in water is called:
a. Pelagic zone
b. Benthic zone
c. Lentic one
d. Littoral zone
The answer is the option (d) Littoral zone
The littoral zone is the name given to the shallow coastal area. Light is present throughout this area. Producers are therefore present in every part of this zone, from the top to the bottom. There is rooted vegetation along the shore. From the top to the bottom of this zone, consumers are also accessible. Hence, (d) is the correct option.
