# The correct sequence of plants in a hydrosere is: Option 1) Volvox $\rightarrow$ Hydrilla $\rightarrow$ Pistia $\rightarrow$ Scirpus $\rightarrow$ Lantana $\rightarrow$ Oak Option 2) Pistia $\rightarrow$ Volvox $\rightarrow$ Scripus $\rightarrow$ Hydrilla $\rightarrow$ Oak $\rightarrow$ Lantana Option 3) Oak $\rightarrow$ Lantana $\rightarrow$ Volvox $\rightarrow$ Hydrilla $\rightarrow$ Pistia $\rightarrow$ Scirpus Option 4) Oak $\rightarrow$ Lantana $\rightarrow$ Scirpus $\rightarrow$ Pistia $\rightarrow$ Hydrilla $\rightarrow$ Volvox

As discussed in

sere(s) -

The entire sequence of communities that successively change in a given area are called sere(s).

- wherein

The individual transitional communities are termed seral stages or seral communities. In the successive seral stages there is a change in the diversity of species of organisms, increase in the number of species and organisms as well as an increase in the total biomass.

A hydrosere is a plant succession which occurs in an area of fresh water.

Option 1)

Volvox $\rightarrow$ Hydrilla $\rightarrow$ Pistia $\rightarrow$ Scirpus $\rightarrow$ Lantana $\rightarrow$ Oak

This solution is correct

Option 2)

Pistia $\rightarrow$ Volvox $\rightarrow$ Scripus $\rightarrow$ Hydrilla $\rightarrow$ Oak $\rightarrow$ Lantana

This solution is incorrect

Option 3)

Oak $\rightarrow$ Lantana $\rightarrow$ Volvox $\rightarrow$ Hydrilla $\rightarrow$ Pistia $\rightarrow$ Scirpus

This solution is incorrect

Option 4)

Oak $\rightarrow$ Lantana $\rightarrow$ Scirpus $\rightarrow$ Pistia $\rightarrow$ Hydrilla $\rightarrow$ Volvox

This solution is incorrect
