Who replaces the phytoplanktons in a hydrarch succession?
(b) Rooted-submerged plants
The question was posed to me in exam.
I’d like to ask this question from Ecosystem topic in division Ecosystem of Biology – Class 12
Right answer is (b) Rooted-submerged plants
The explanation: A hydrarch succession starts with the colonization of small phytoplanktons. These phytoplanktons, later with time are replaced by rooted-submerged plants in a hydrarch succession. Some examples of the rooted-submerged plants are Ceratophyllum, Chara, Elodia, Potamogeton, etc.
