Minzenmayer AP Biology CHW 1.3 tem 5 Part F- Zonation in lakes and oceans Zones In lakes and oceans are delineated by depth, distance from shore, ox ight penetration ferent zoes have derent physical and chemical charadtwiate Drag the labels to their correct targets on the diagrams below. Use the pink i View Available Hint(s) labels for the pink targets and the blue labels for the blue targets edends to edge of benthic zone ight penetraies heremay be rooted here Marne Zonation imnetic zone Part a Turnover in semperate lakes Type here to searchExplanation / Answer
Q1) Different zones of lakes and oceans in the question the labels are as below
a) Fresh water plants may be rooted here
b) Littoral zone
c) Limnetic zone
d) Alternately dry and submerged
e) Extends to edge of the continental shelf
f) Generally low nutrient level
g) Light penetrates here
h) No photosynthesis occurs here
i) Benthic zone.
These are the various layers and functions of Lake and marine ecosystem.
Explanation:-
In lake ecosystem The littoral zone is the areas near to shore, here light penetrates as a result it allows fresh water plants to grow, so it is thought that in littoral zone plants may be grown.
Limnetic zone is the zone below littoral zone and extends up to light compensation level, it gets its oxygen content from the phytoplankton present in it.
The intertidal zone of ocean is the area of high tide and low tide. It bridges the gap between land and water or it is the zone where water meets land. It is alternatively dry and submerged.
Neritic zone is the zone in ocean which extends to the continental shelf, it contains runoff from land flow, so contains nutrients for plankton.
Oceanic zone:- It lies below continental shelf, it contains oceans 65% open water. In this zone there is thermal stratification where warm and cold waters mix due to oceanic current, here generally there is low nutrient level so it is less productive part of marine biome.
Photic zone of lake:- It is also known as sunlight zone, it is the uppermost layer of lake, and ocean, where light penetrates. Here almost all photosynthesis occurs.
Aphotic zone:- It is the portion of lake, where there is very less sunlight, less than 1% sunlight penetrates here, as a result there is no photosynthesis.
Benthic zone in ocean:- It is the lowest part of a lake or ocean, organisms living in this zone are called benthos. Benthic organisms living in this zone are food for bottom feeding animals, benthic organisms help in determining water quality, they are ecologically significant.
These are the various zones of lakes and oceans and their characteristic features.
