Planktonissa

Planktonissa is a term that refers to the collective noun for plankton. Plankton are microscopic or near-microscopic organisms that drift in the sea or freshwater. They form the base of many aquatic food webs, meaning that other organisms depend on them for survival. Plankton can be broadly categorized into two groups: phytoplankton and zooplankton. Phytoplankton are plant-like organisms, often microscopic algae, that produce their own food through photosynthesis. They are responsible for a significant portion of the Earth's oxygen production. Zooplankton are animal-like organisms, which can range from single-celled protozoa to small crustaceans and larval forms of larger animals. They feed on phytoplankton or other zooplankton. The distribution and abundance of planktonissa are influenced by factors such as water temperature, nutrient availability, and ocean currents. Changes in planktonissa populations can have far-reaching effects on marine ecosystems and global biogeochemical cycles. Their study is crucial for understanding ocean health and predicting the impacts of climate change.
