Explain succession of plants.
Based on the nature of the habitat whether it is water (or very wet areas) or it is on very dry areas succession of plants is called hydrarch or xerarch.
Hydrarch succession takes place in wet areas and the successional series progress from hydric to the mesic condition.
As against this xerarch succession takes place in dry areas and the series progress from xeric to mesic condition.
Hence both hydrarch and xerarch successions lead to medium water conditions (mesic) - neither too dry (xeric) nor too wet (hydric).
The species that invade a bare area are called pioneer species.

The rate of decomposition of detritus is affected by the abiotic factors like availability of oxygen, $\mathrm{pH}$ of the soil substratum, temperature etc. Discuss.
