उत्तर
The following are the different seral stages in hydrach succession from pioneer species to climax community:
- Small phytoplankton are the primary successional species in aquatic settings.
- Phytoplankton are gradually replaced by rooted-submerged plants (e.g. Hydrilla), rooted-floating angiosperms (e.g. Lotus), free-floating plants (e.g. Pistia), reed swamp (e.g. Typha), marsh-meadow (e.g. Cyperus), scrub (e.g. Alnus), and finally trees (e.g. Quercus).
- The climax community would be a forest. The sea body transforms into land throughout time.
