Step 3 - Slice the squash. Just take a sharp knife and cut of both ends (about 1/4 of an inch, or half the width of an average woman's little finger) Slice 1/2-inch thick slices. Prepare quickly, (if you leave it sit out cut up for more than a half hour, it will start to discolor).
The benthic zone begins at the edge of the sea at the intertidal zone, extends out along the continental shelf, and continues down the continental slope to the abyssal plain, thousands of meters below sea level.
The benthic zone is the deepest part of the body of water, and actually can overlap with the littoral zone. For example, a few feet from the shore of a lake, the sediment can be considered to be in both the benthic and littoral zone. But when you consider the sediment in the deepest area, that would be the benthic zone only.
