Detailed explanation-3: -Phytoplankton While phytoplankton may not be the most well-known, they are likely the most plentiful marine plant. Phytoplankton are a critical part to all aquatic ecosystems. As they are microscopic, you won’t be able to see them with the naked eye, but rest assured, they are hard at work.
