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.

it has to be understood that the sea water contains a huge amount of sodium and chlorine ions and if they enter the cell of the atlantic cod fish, the cell will shrivel and the fish will die. to avoid such a condition, the fish uses active transport for the purpose of removing the ions against the gradient.

explanation:

the atlantic cod is not a maritime osmoconformer. its native application of salts is less than that of the seawater it lives in. it is continually falling water from the gills to the ocean via osmosis.

countering that, the fish is going to be swallowing seawater. but since its internal collection of salts is lower than seawater, the fish will want to go free of excess salt, and since that's going upon a gradient, then active transport, requiring energy, must be used to pump out the salt. much marine fish use the organs to filter out the salt and these fish discharge very straight urine.
