In hydrosere, the stages that come before and after the reed-swamp stage are, respectively,

Options

  1. Aphytoplankton stage and submerged stage
  2. Bsubmerged stage and submerged free-floating stage
  3. Csubmerged free-floating plant stage and marsh-meadow stage
  4. Dsubmerged free-floating plant stage and scrub stage

Correct answer

C. submerged free-floating plant stage and marsh-meadow stage

Step-by-step solution

Ecological succession is a predictable process; therefore, it can be predicted which stage will come before or after any stage. The correct sequence of succession is: Phytoplankton stage → submerged plant stage → submerged free floating plant stage → reed-swamp stage → marsh meadow stage → scrub stage → forest stage.
