Question

Which of the following is the correct trend of succession in hydroseric succession?

• A. Phytoplankton $\to$ Rooted submerged $\to$ Reed swamp $\to$ Sedge meadow.
• B. Phytoplankton $\to$ Reed swamp $\to$ Rooted submerged $\to$ Sedge meadow.
• C. Phytoplankton $\to$ Sedge medow $\to$ Reed swamp $\to$ Sedge meadow.
• D. Rooted submerged $\to$ Phytoplankton $\to$ Reed swamp $\to$ Sedge meadow.

Answer 1

The correct option is A Phytoplankton $\to$ Rooted submerged $\to$ Reed swamp $\to$ Sedge meadow.

There are main eight stages of hydroseric succession in plants. These are Phytoplankton stage, rooted submerged stage, floating Stage, reed swamp stage, sedge meadow stage, alder or willow carr stage, wood land stage and climax woodland stage. Phytoplankton stage includes autotrophic diatoms, phytoflagellates, cyanobacteria. Rooted submerged stage includes species like Myriophyllum, Hydrilla, Ceratophyllum. Foating plants are rooted in the mud, however leaves float on the surface of the water. Example includes Water-lilies. Reed swamp stage is also called as amphibious stage. It includes typha, sagittaria. Sedge meadow plants include plants those are newly emerged from water and highly vulnerable to drying out. Willow carr plants include rushes, ferns and small flowering herbs. Woodland plants can tolerate sunlight and water logged condition. These include Cornus, Cephlanthus. Climax plants include Oak, Ash, Beech.

Thus, the correct answer is option A.
