Q. Fill in the missing stages (A to D) in the given primary hydrarch succession. Phytoplankton $\rightarrow$ (A) $\rightarrow$ (B) $\rightarrow$ (C) $\rightarrow$ Marsh-meadow stage $\rightarrow$ (D) $\rightarrow$ Forest plant stage
A) A-Read-swamp-stage, B-Sub-merged plant stage, C-Sub-merged free-floating plant stage, D-Scrub stage
B) A-Sub-merged plant stage, B-Sub-merged free-floating plant stage, C-Read-swamp-stage, D-Scrub stage
C) A-Scrub stage, B-Sub-merged plant stage, C-Read-swamp-stage, D-Sub-merged free-floating plant stage
D) A-Read-swamp stage, B-Scrub stage, C- Sub-merged plant stage, D-Sub-merged free floating plant stage
Explanation
Phytoplankton $\rightarrow$ Submerged plant stage A $\rightarrow$ Submerged free floating plant stage B $\rightarrow$ Read swamp stage C $\rightarrow$ Marsh-meadow stage $\rightarrow$ Scrub stage D $\rightarrow$ Forest plant stage
