Learn how seagrasses, mangroves, and other aquatic plants evolved to tolerate low light levels, anaerobic and nutrient-poor sediments, and the difficulty of getting CO2 into submerged leaves and stems. They also benefit surrounding ecosystems by keeping excess nutrients from the ocean, trapping river and ocean-floor sediments, and providing habitat and protection for animals.
