What is the Intertidal zone exposed to when ocean tides go out?
Darkness
Air
Constant submersion in water
High temperatures
Organisms in the Intertidal zone need to have certain adaptations to survive because:
The water is very salty.
They are exposed to breaking ocean waves.
It is very dark and cold.
There is an abundance of nutrients.
What characterizes the water in the Abyssal zone?
Warm and light
Dense, cold, and salty
Shallow and nutrient-rich
Fresh and oxygenated
How do nutrients reach animals in the Abyssal zone?
Through underwater plants
Via thermal vents
As marine snow falling from above
Carried by strong currents
What happens to conditions such as pressure, temperature, and light as you go deeper in the Pelagic zone?
They all increase.
They remain constant.
They all decrease.
Pressure increases, temperature and light decrease.
What is the Benthic Zone?
The ecological region at the highest level of a body of water
The ecological region at the lowest level of a body of water
The ecological region at the surface of a body of water
The ecological region in the middle layer of a body of water
Where does the Benthic Zone start?
In the open ocean
At the shoreline and goes down until it is deep
At the continental shelf
At the water's surface
What does the Benthic Zone encompass?
Only the water column
Only the surface of the water
The sediment surface and subsurface layers
The atmospheric layer above the water
Why is the Benthic Zone vital for the health of aquatic ecosystems?
It provides sunlight for photosynthesis
It is the warmest part of the water body
It contains microscopic benthic organisms that act as a source of food for bottom-feeding animals
It is the primary source of oxygen for the water body
