Which term describes marine plants that form underwater meadows in shallow seas?

• A. Agnatha
• B. Plankton Net
• C. Sea Grass
• D. Animal

Answer: (C)

Sea grass are marine flowering plants that form underwater meadows in shallow seas. They are not algae or animals, but angiosperms that grow rooted in sediment with leaves reaching the light for photosynthesis. These seagrass beds create dense habitats that stabilize sediments, help protect shorelines, and provide nurseries for many marine species. The other options don’t fit because they describe a jawless fish (Agnatha), a sampling tool (Plankton Net), or a broad category of living beings (Animal), none of which are plants that form underwater meadows.
