Question
Succession in aquatic habitat.
✓
Answer
In aquatic habitats the pioneer species in primary succession are the small phytoplankton.
Phytoplankton are replaced by rooted- submerged plants (e.g. Hydrilla), rooted- floating angiosperms (e.g. Lotus) followed by free-floating plants (e.g.Pistia), then reed swamp (e.g. Typha), marsh-meadow (e.g. Cyperus), scrub (e.g. Alnus) and finally the trees (e.g. Quercus) in a very systematic and gradual way.
The climax again would be a forest. With passage of time, the water body is converted into land.
