Which ecosystem has the greatest primary productivity ocean beds algal beds and reefs or estuary?
According to Whittaker (1975) of the three ecosystems, algal beds and reefs have the highest average primary productivity of 2500 g m-2y-1. Esturies are also fairly productive areas, averaging 1500 g m-2y-1. The open ocean on the other hand is a relatively unproductive system, averaging 125 g m-2y-1.However, if you look at the total productivity, and not the averages, the picture changes substantially. Now the open ocean contributes the most to the total global productivity due to vastly greater area than either esturies or algal beds and reefs. Indeed, with just 1.2 x 109t-1 algal beds and reefs contribute the least to the total global productivity.It is also worth noting that continental shelf areas have a higher productivity than open ocean, but contribute less to the global total, again because of reduced area.All figures taken fromWhittaker RH (1975) Communities and Ecosystems.

More than 90 percent of the primary productivity in the ocean is accomplished by?
photosynthesis

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.
Different kinds of ecosystems?
There are many different types of ecosystems on earth that are categorized into three major classes of ecosystems that include freshwater, ocean, and terrestrial. Ocean ecosystems are the largest covering 75 percent of the earth.

Which primary producers in most ocean ecosystems and that which produce energy through photosynthesis?
Phytoplankton are single celled primary producers present in the sunlit upper layers of the ocean. These include diatoms, cyanobacteria and dinoflagellates etc. All life depends on these primary producers to acquire entry through photosynthesis.
What is the biggest ecosystems in the world?
The ocean

Why don't plants and animals in river ecosystems usually also live in the ocean?
because river ecosystems and ocean ecosystems are way different so they could not survive in the wild(in this case the ocean) hope this helped at least a bit.
What is the function of phytoplankton in ocean ecosystems?
Producer.
Where can ocean ecosystems be found?
In any ocean...? Not sure what you mean- anywhere! There are ecosystems from the coral reefs to the depths of the ocean! There are very very few places where there are NOT any ecosystems or population of some kind.
