PHYTOPLANKTON ARE PLANTS. THEY NEED SUNLIGHT, WHICH IS NON EXISTANT AT THE OCEAN'S DEPTHS.
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.
Oxygen is found at high levels near the surface of the ocean due to plant photosynthesis. Plants in the ocean, like phytoplankton, produce oxygen as a byproduct of photosynthesis, leading to high concentrations of oxygen in the surface waters.

The first link in the ocean food chain is phytoplankton. These microscopic organisms convert sunlight into energy through photosynthesis and serve as the primary producers of the ocean ecosystem. Phytoplankton are then consumed by zooplankton, which are in turn eaten by small fish, and the food chain continues from there.
Upwelling occurs when wind pushes surface ocean water away from the coastline, causing deeper, colder, nutrient-rich water to rise and replace it. This brings nutrients to the surface, fueling the growth of phytoplankton and supporting a productive marine ecosystem.
Phytoplankton are primarily found on the ocean surface because they need sunlight for photosynthesis. Sunlight penetrates only the upper layers of the ocean, so phytoplankton stay near the surface to access this light. They also require nutrients that get transported to the surface through upwelling or mixing processes.

Phytoplankton live near the surface of the ocean because they need sunlight like all green plants. They also need water and nutrients to live. Phytoplankton use water and CO2 to grow, but phytoplankton still need other vitamins and minerals, like iron to survive. When the surface of the ocean is cold, the deeper parts of the ocean bring these nutrients to the surface and the plankton live. But, when the surface of the ocean is warm, as in El Niño, the ocean does not bring as many of these essential nutrients and the phytoplankton die. That causes a major problem because phytoplankton are at the base of the food chain. So, when the population of phytoplankton is reduced almost the entire food chain is effected.
Phytoplankton, which is a microscopic and autotrophic organism. There are trillions of phytoplankton in the ocean.
Actually not all plankton does, there are many types of plankton. Phytoplankton are the type that must be near the surface to survive because they are similar to plants in that they must be in an environment in which photosynthesis can occur.
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.
