Choose the correct sequence of biotic succession for hydrosere.

Options

  1. APhytoplankton → Floating stage → Submerged stage → Sedges → Reed swamp stage → Bushes → Bushes → Trees
  2. BZooplankton → Floating stage → Submerged stage → Reed swamp stage → Sedges → Bushes → Trees
  3. CPhytoplankton → Zooplankton → Submerged stage → Floating stage → Reed swamp stage → Sedges → Bushes → Trees
  4. DZooplankon → Submerged stage → Floating stage → Sedges → Reed swamp stage → Bushes → Trees

Correct answer

C. Phytoplankton → Zooplankton → Submerged stage → Floating stage → Reed swamp stage → Sedges → Bushes → Trees

Step-by-step solution

Hydrosere is the series of biotic communities that form/develop in a newly formed aquatic system like a lake or pond. Hydrosere has several stages of succession as below - Phytoplanktons (producers) → zooplanktons (consumer) → rooted submerged hydrophytes → free-floating hydrophytes → reed swamps → sedges or marsh-meadow stage → woodland or scrub stage → trees (climax forest).
