Plankton communities refer to the diverse collections of plankton found in aquatic ecosystems. Plankton are small or microscopic organisms that drift or float in the water column, unable to swim effectively against currents. These communities are broadly categorized into phytoplankton and zooplankton. Phytoplankton are photosynthetic algae, forming the base of many aquatic food webs, analogous to plants on land. Zooplankton, on the other hand, are small animals or the larval stages of larger animals, and they consume phytoplankton or other zooplankton.

The composition and abundance of plankton communities are highly dynamic, influenced by factors such as nutrient availability, temperature, light, salinity, and water movement. Seasonal changes often lead to distinct plankton blooms, particularly of phytoplankton, when conditions are favorable for growth. These blooms are crucial for supporting higher trophic levels, including fish, marine mammals, and seabirds.

Plankton communities are essential for ecosystem health and global biogeochemical cycles. Phytoplankton play a vital role in the Earth's carbon cycle by absorbing carbon dioxide through photosynthesis and producing a significant portion of the world's oxygen. Changes in plankton community structure can indicate shifts in environmental conditions, such as pollution or climate change, making them important indicators for ecological monitoring. The study of plankton communities, or planktology, provides critical insights into the functioning and health of aquatic environments.
