Because there is no light. Sunlight doesn't reach that far down.

What role do chemosynthetic bacteria play in deep-sea volcanic-vent ecosystems?
It serves as a food source to organisms in the deep water
Why do organisms living in the pelagic zone below 200 meters depend on organisms living above that depth to supply their energy?
Plant photosynthesis is the primary source of nutrients in every ecosystem. Deep in the ocean, where little or no sunlight is present, photosynthesis is impossible. Thus, organisms in deep water ecosystems depend on detritus (discarded waste) and other organic matter that drifts down from (and is generated) nearer to the surface, or on species that migrate back and forth.
Photosynthesis can take place only near the surface of a very deep body of water.?
False.
What are the four types of water ecosystems?
The four types of Aquatic Ecosystems are - 1. Oceans are the largest of the ecosystems covering more than 70 % of the earth's surface. 2. Freshwater bodies like lakes and ponds 3. Flowing fresh water like rivers and streams 4. Wetlands with wet soil and plants that grow in this type of soil
What is a marine ecosystem?
Marine ecosystems are among the largest of Earth's aquatic ecosystems. They include oceans, salt marsh and intertidal ecology, estuaries and lagoons, mangroves and coral reefs, the deep sea and the sea floor. They can be contrasted withfreshwater ecosystems, which have a lower salt content.
Why cant photosynthetic organisms grow in the deep water zone of a lake?
They can't grow their because no sunlight reaches.
What role do chemosynthetic bacteria play in deep-sea volcanic-vent ecosystems?
It serves as a food source to organisms in the deep water
How it is possible for phytoplankton to perfom photosynthesis under water?
Water doesn't inhibit photosynthesis as long as it is not too deep for adequate light penetration.
What plants are found in the deep sea water?
None as there is no light for photosynthesis!
Photosynthesis can take place only near the surfaces of a very deep body of water?
Yes of course. Photosynthesis need light to take place. Light does not reach very deep.
Where in waters biome can photosynthesis occur?
If in shallow water, the plants that grow on the bottom, but if on deep water, on floating algae.
What are ecosystems in the ocean called?
Ecosystems in the ocean are called marine ecosystems. They can be tidal, coastal, or deep sea. They are typically salty.

False.
In Pokemon emerald What is the deep patch of water which you cant dive into?
you have to find the darkest patches of water to dive down in

Heat from Earth's interior.
