What will be the $P/R$ ratio of a climax community and a pioneer community. What explanation could you offer for the changes seen in $P/R$ ratio of a pioneer community and the climax community.

Production / Respiration late $\left(\frac{\mathrm{P}}{\mathrm{R}}\right)$ ratio which Gross production and total group respiration and net group respiration when $\mathrm{P} / \mathrm{R}=1$ one stable result.
This result may be instantaneously daily one or over a longer period. If $\mathrm{P} / \mathrm{R}$ is persistantly greater or less than/then organic matter either accumulates or is depleted respectively.
| Pioneer community | Climax community |
| $(1)$The species which fix base part is called initial species, generally it is lichen rocks. | $(1)$It is the final group develops in its regions. |
| $(2)$Phytoplanktons are present in second ecosystem. | $(2)$It is fixed in such a region where many non nucleared groups are seen |
| $(3)$The rate of $\frac{\mathrm{P}}{\mathrm{R}}$ at pioneer community will be more than one. | $(3)$The rate of $\frac{\mathrm{P}}{\mathrm{R}}$ at climax community will be one. |
