planktoniaktiivsuse

Planktoniaktiivsus refers to the collective biological activity of plankton. Plankton are microscopic or macroscopic organisms that drift in bodies of water, lacking the ability to swim against prevailing currents. This group includes a vast diversity of life, from tiny bacteria and phytoplankton (algae) to zooplankton such as crustaceans and larval fish. Their activity is fundamental to aquatic ecosystems.

Phytoplankton forms the base of most aquatic food webs through photosynthesis, converting sunlight, carbon dioxide, and nutrients into organic matter and oxygen. This process is often referred to as primary production. The rate at which phytoplankton grow and reproduce, their "activity," directly influences the amount of food available for zooplankton and subsequently for larger organisms. Zooplankton, in turn, consume phytoplankton and smaller zooplankton, playing a crucial role in energy transfer through the food web.

Planktoniaktiivsus is highly dynamic and influenced by environmental factors like temperature, light availability, nutrient concentrations, and water currents. Seasonal changes, upwelling events, and human-induced changes in water quality can all significantly impact the abundance, distribution, and metabolic rates of plankton communities. Monitoring planktoniaktiivsus is therefore essential for understanding the health and productivity of oceans, lakes, and rivers, as well as for tracking global biogeochemical cycles, particularly the carbon cycle.
