Which zone in a lake would you expect to be dominated by emergent plants?

Littoral zone

Explanation:

The littoral zone act as a connection between pelagic zone and terrestrial ecosystem. The large amount of species diversity is observed in littoral zone. The emergent plants are rooted plants that generally float over the surface but few plants are submerged in water.

The emergent plants are the marcrophytes. These plants are dominant in the littoral zone of lake. The fresh water marshes are commonly inhabited by emergent plants (Typha). The emergent plants have high primary production rate thus increasing the productivity of fresh water marshes.

the correct answer, according to e2020, is the second choice there is an occluded front in region a and a cold front in region b.
