What is phytoplanket?

Phytoplankton are microscopic, photosynthetic organisms found in aquatic environments, including oceans, rivers, and lakes. They play a crucial role in the ecosystem by producing oxygen and serving as the foundation of the aquatic food web, supporting various marine life. Phytoplankton mainly consist of algae, cyanobacteria, and other single-celled organisms. Their abundance and diversity significantly influence global carbon cycling and climate regulation.
