Question:

Arrange the following steps of primary succession in the correct sequence:

(A) Marsh-meadow stage
(B) Submerged free floating plant stage
(C) Forest
(D) Phytoplankton
(E) Scrub stage

Choose the correct answer from the options given below:

Options:

(B) → (A) → (D) → (C) → (E)

(D) → (B) → (A) → (E) → (C)

(C) → (D) → (B) → (A) → (E)

(E) → (C) → (B) → (A) → (D)

Correct Answer:

(D) → (B) → (A) → (E) → (C)

Explanation:

The correct answer is Option (2) → (D) → (B) → (A) → (E) → (C)

(D) Phytoplankton

(B) Submerged free floating plant stage

(A) Marsh-meadow stage

(E) Scrub stage

(C) Forest

In primary succession in water, the pioneers are the small phytoplanktons, which are replaced with time by rooted-submerged plants, rooted-floating angiosperms followed by free-floating plants, then reed- swamp, marsh-meadow, scrub and finally the trees. The climax again would be a forest. With time the water body is converted into land.
