Phytoplankton are microscopic marine plants. P hytoplankton, also known as microalgae, are similar to land-based plants in that they contain chlorophyll and require sunlight in order to live and grow. Most phytoplankton are buoyant and float in the upper part of the ocean, where sunlight penetrates the water. Phytoplankton also require inorganic nutrients such as nitrates, phosphates, and sulfur which they convert into proteins, fats, and carbohydrates.
Plankton is the mass of microscopic plants and animals that float near the surface of large lakes and oceans. Phytoplankton is the plant matter while zooplankton is the animal component. Zooplankton feeds on phytoplankton and acts as a link in the food chain between plants and larger animals.Without these tiny creatures to graze on the phytoplankton, there would be a catastrophic collapse of the entire marine ecosystem and bioweb.ooplankton feeds on phytoplankton and acts as a link in the food chain between plants and larger animals.
