The sequence of communities of primary succession in water is?

1. Phytoplankton, sedges, free-floating hydrophytes, rooted hydrophytes, grasses and trees
2. Phytoplankton, free-floating hydrophytes, rooted hydrophytes, sedges, grasses and trees
3. Free-floating hydrophytes, sedges, phytoplankton, rooted hydrophytes, grasses and trees
4. Phytoplankton, rooted submerged hydrophytes, floating hydrophytes, reed swamp, sedges, meadow and trees

Correct answer: Phytoplankton, rooted submerged hydrophytes, floating hydrophytes, reed swamp, sedges, meadow and trees

Solution

In aquatic primary succession, the community changes as sediment accumulates and the water becomes shallower. The correct order starts with phytoplankton, then rooted submerged hydrophytes, followed by floating hydrophytes, reed swamp, sedges, meadow, and finally trees.
