Phytoplankton need to float primarily to access sunlight for photosynthesis, which is essential for their growth and survival. Being suspended in the upper layers of water allows them to maximize exposure to light while also being in nutrient-rich zones. Additionally, floating helps them remain within the euphotic zone, where light penetrates, enabling them to thrive in aquatic ecosystems.
No. They are microscopic plants that float freely in seawater.
They aren't very dense, so they float.
Phytoplankton
the answer is phytoplankton or plankton
No because phytoplankton need sunlight to photosynthisize.
They are called phytoplankton. These microscopic algae are crucial to the marine food web as they serve as the primary producers, converting sunlight into energy through photosynthesis.
the top layer of the ocean is called the Epipelagic
phytoplankton
Absolutely.
Sunlight and water.
the relationship is that seens phytoplankton need sunlight to survive and phytoplankton are the base of the food chain they connect to sun to phytoplankton to other sea life
No phytoplankton would have to be plants and dinoflagellates are animals and if regarded as part of the plankton would need to be called zoo-plankton.
