Who replaces the free-floating plants in a hydrarch succession?
(a) Rooted-submerged plants
(b) The reed-swamp
(c) Free-floating angiosperms
I have been asked this question at a job interview.
Question is from Ecosystem topic in portion Ecosystem of Biology – Class 12
Correct option is (b) The reed-swamp
Best explanation: The sequence of successional stages occurring in water is known as hydrarch succession or hydrosere. The free-floating plants with time are replaced by the reed-swamp in a hydrarch succession. Some examples of the reed-swamp plants are Bothrioclova, Phragmites (Reed), Typha, etc.
