Marshes are among the most biologically productive ecosystems on Earth. High nutrient input (often from surrounding land or water bodies) and abundant sunlight in shallow water fuel rapid plant growth. Therefore, the statement that they are the least productive natural environments is incorrect.

– Wetlands like marshes are known for their high primary productivity (conversion of mineral matter to organic matter by plants).
– They perform important ecological functions, including nutrient cycling, water purification (acting as sinks for pollutants and sediments), and providing habitat for diverse wildlife.
– Marshes contribute significantly to the aesthetic value of landscapes.

Other highly productive ecosystems include estuaries, coral reefs, and tropical rainforests. Less productive environments typically include deserts, open oceans, and polar regions.
