Question

select the intertidal zone ecosystem.
this ecosystem has:
daily flooding and draining of seawater
water that is rich in nutrients
many different types of organisms
this ecosystem has:
salty water
deep water that is far from shore
a small amount of sunlight
this ecosystem has:
land that is covered with water for most of the year
many trees and shrubs
soil that is rich in nutrients

Explanation:

The intertidal zone ecosystem is characterized by daily flooding and draining of seawater (due to tides), nutrient - rich water (as tides bring in nutrients), and a high diversity of organisms (as various species adapt to the changing conditions). The first ecosystem description matches these characteristics. The second ecosystem with deep water far from shore and little sunlight is more like an open - ocean or deep - sea ecosystem. The third with land covered in water most of the year and many trees/shrubs is a wetland (like a swamp) ecosystem.

Answer:

The first ecosystem (with daily flooding and draining of seawater, nutrient - rich water, and many different types of organisms) is the intertidal zone ecosystem.
