Question

What is the main reason why phytoplankton are found near the top ten feet of the ocean and not deeper?

Answer

Phytoplankton are mostly found near the top ten feet of the ocean because they depend on sunlight for photosynthesis, which is crucial for the production of their own food. Because they are autotrophic organisms, they play an important role in the marine food chain as they provide nutrients to other marine organisms. Additionally, phytoplankton are important in the medical field as supplements for lowering muscle damage and sustaining physical performance.

Phytoplankton are critical components of marine ecosystems as they produce oxygen, serve as a source of food for marine organisms, and regulate the climate. They are mainly limited to the top layer of water streams where sunlight can penetrate, allowing them to carry out their photosynthetic activities to synthesize food.
