Question

select the abyssal zone ecosystem.
this ecosystem has:
salty water
deep water that is far from shore
a small amount of sunlight
this ecosystem has:
very deep water at the bottom of the ocean
no sunlight
organisms that crawl or stick to the ground
this ecosystem has:
water that is low in salt and rich in oxygen
flowing water
organisms that swim or stick to rocks

Explanation:

The abyssal zone is the bottomless layer of the ocean. It is very deep, has no sunlight, and the organisms there crawl or stick to the ground. The first option has a small amount of sunlight which is not characteristic of the abyssal zone. The third option has low - salt water which is not ocean water. The second option with very deep water at the bottom of the ocean, no sunlight, and organisms that crawl or stick to the ground matches the abyssal zone.

Answer:

The second ecosystem (with very deep water at the bottom of the ocean, no sunlight, and organisms that crawl or stick to the ground) is the abyssal zone ecosystem.
