Question

In hydrosere succession, which stage comes just before the sedge meadow stage?

• A. Rooted submerged stage
• B. Phytoplankton stage
• C. Reed swamp stage
• D. Climax stage

Hint:

Hydrosere progression involves a gradual replacement of aquatic plants with terrestrial vegetation, as water levels decrease and soil formation occurs.

Answer 1

The Correct Option is C

Phase 1: Grasping hydrosere succession
Hydrosere describes ecological succession originating in water bodies and advancing to a stable terrestrial state. Each phase involves alterations in predominant flora and environmental conditions.Phase 2: Enumerating hydrosere succession stages
The standard phases of hydrosere succession include:1. Phytoplankton phase (aquatic initiation)2. Submerged plant phase (submersed rooted flora)3. Floating plant phase (rooted floating flora)4. Reed marsh phase (emergent flora)5. Sedge marsh phase (herbaceous plants in shallow water or damp substrate)6. Forest phase (woody flora)7. Climax phase (terrestrial flora, e.g., forest or grassland)Phase 3: Preceding phase to sedge marsh stage
The sedge marsh phase features sedges and other herbaceous species. The reed marsh phase, dominated by emergent plants like reeds and cattails, precedes this stage.Summary: The phase immediately prior to the sedge marsh stage is the reed marsh stage.
