Lake
Body of standing water so deep that no plants can grow on the bottom.

Photic Zone
The shallow water part of the ocean from the low tide zone to the edge of the continental shelf.
Aphotic Zone

Draggable itemCorresponding Item
C
Supralittoral
A
Littoral
B
Sublittoral
1

The majority of organisms that live in the ocean are found in the Neritic and Photic zones beacuse there is more oxygen and light available.
