Explain the different steps of xerarch succession occurring in nature. |
|
Answer» Xerarch Succession in Nature: • Lichens are the pioneer species on a bare area. • The lichen secretes some acids to dissolve rock and help in weathering and soil formation. • Later, some small bryophytes invade and hold the small amount of soil. • The bryophytes are succeeded by herbs, shrubs and ultimately big trees. • At last, a stable climax forest is formed. • The xerophytic habitat gets converted into a mesophytic one. |
