The area between 200 and 1,000 meters (656 and 3,280 feet) is the mesopelagic or “twilight” zone.
Explanation:
Light intensity in this zone is severely reduced with increasing depth, so light penetration is minimal. About 20 percent of primary production from the surface falls down to the mesopelagic zone.
It’s mass and speed. This is because the equation for Kinetic energy is KE=1/2mv^2
The answer is C.
Organism, population, community, ecosystem, biosphere
I recommend reading a passage about it. Hope this helps!
