the niche of the zooplankton is providing filter feedings for other organisms
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.
An increase in ocean phytoplankton can enhance the carbon cycle by boosting carbon fixation through photosynthesis, as these microorganisms absorb carbon dioxide (CO2) from the atmosphere. This process leads to greater sequestration of carbon in the ocean, potentially mitigating climate change. Additionally, when phytoplankton die, they sink to the ocean floor, effectively trapping carbon in deep waters for extended periods. However, changes in phytoplankton populations can also affect nutrient cycling and marine ecosystems, highlighting the complexity of their role in the carbon cycle.
Native plants of the ocean include seaweeds such as kelp, seagrasses like eelgrass, and phytoplankton such as diatoms. These plants play important roles in marine ecosystems by providing food and habitat for a variety of organisms.
Phytoplankton are the autotrophs that are the main producers for the upper layers of the ocean.This is because the upper layers of the ocean provide the most sunlight, which is what phytoplankton need in order to perform photosynthesis.

Biotic, they are living because they are a type of plankton.

Phytoplankton, which is a microscopic and autotrophic organism. There are trillions of phytoplankton in the ocean.
The answer to your question is phytoplankton
Primary producers in most ocean ecosystems are phytoplankton, which are microscopic algae that use photosynthesis to produce energy. Phytoplankton play a crucial role in marine food chains by converting sunlight into organic matter that fuels the rest of the ecosystem.

There are a wide variety of ocean creatures which are known to eat phytoplankton. However, krill are believed to be the main organisms which feed on phytoplankton.

No because phytoplankton need sunlight to photosynthisize.
