Answer» Correct Answer - C Primary succession (or prisere) is the biotic succession that occurs on a previously sterile or primarily bare area. Newly exposed sea floor, igneous rocks, sand dunes, new cooled lava sediments or newly submerged areas are some of the examples of primary bare area. Soil and humus is absent at the beginning of primary succession and reproductive structures of any previous community and primary succession takes a long time for completion. |
