d) Primary succession occurs where a series of communities with different species develop in places containing soil. Secondary succession involves the gradual establishment of biotic communities in lifeless areas where is no soil.

Answer 1

Answer : a) Primary succession involves the gradual establishment of biotic communities in lifeless areas where is no soil. Secondary succession occurs where a series of communities with different species develop in places containing soil.

Explanation: One of the two types of ecological and biological succession of plant life is primary succession, that occurs in an environment in which the new substrate is completely devoid of soil, vegetation and other organisms such as a lava flow or in an area that is formed by the deposits left behind from a retreated glacier. On the other hand, a secondary succession occurs on a land or substrate that previously contained soil and therefore supported vegetation before the occurrence of an ecological disturbance from the smaller things like hurricanes, floods, tornadoes, and wild forest fires which destroyed the plant life
