Question

Compare rates of succession: primary succession such as on new lava flow vs secondary succession in a forest that recently burned. A. Primary succession is faster than secondary succession OB. Secondary succession is faster than primary succession C. Primary and secondary succession usually proceed at the same rate because they both followed a large disturbance. D. Succession rates would depend on the number of early arriving facilitator species.

Answer 1

Answer will be option 2 secondary succession is faster than primary succession.

Reason- primary succession is that where life originates from barren land or cold lava where life was not present initially and now life or succession is starting. Since conditions are more harse or unfavourable so origin and continuation of sucessions will take more time.

Secondary succession is that where life was already there but due to natural calamities or human interference life or succession was eliminates so here resuccession will occur at much faster rate as seed or spore or tuber are presents inside the soil which will start succession.

Hope it's clear..thanks
