microplankters

Microplankters are microscopic organisms that play a crucial role in marine ecosystems. They are typically defined as planktonic organisms with a cell size ranging from 20 to 200 micrometers. This group includes a diverse array of organisms such as protozoa, bacteria, and various types of phytoplankton. Phytoplankton, in particular, are photosynthetic microplankters that form the base of the marine food web. They are responsible for approximately half of the Earth's photosynthesis, contributing significantly to the global carbon cycle.

Microplankters are found in all marine environments, from the surface waters to the deep sea. They are essential for nutrient cycling and the production of oxygen. Their small size allows them to be widely distributed and to inhabit various ecological niches. Some microplankters are motile, capable of moving through the water column, while others are non-motile and drift with ocean currents.

The study of microplankters is important for understanding marine ecosystems and climate change. Changes in microplankton populations can indicate shifts in ecosystem health and may influence global climate patterns. Advances in microscopy and molecular biology have greatly enhanced our ability to study these organisms, providing insights into their diversity, distribution, and ecological roles.
