Answer» The correct ANSWER is (b) Phytoplanktons → Rooted-submerged plants → Rooted-floating angiosperms → Free-floating plants → Reed-swamp → Marsh-meadow → Scrub → Forest Easiest explanation: The sequence of successional stages OCCURRING in water is known as hydrarch succession or hydrosere. It MOSTLY starts from phytoplanktons and ends with the formation of a forest. The pioneering SPECIES grow with time leading to a formation of a climax community called a forest.
