Question

which of the statements best describes why primary succession occurs before secondary succession but secondary succession may occur faster and result in higher biodiversity? a primary succession introduces animal species to the area while secondary succession introduces plant species to the area. b primary succession establishes soil in the area while secondary succession allows for recovery of the community after a disturbance. c primary succession increases the moisture and humidity in the area while secondary succession increases the groundcover by plants in the area. d primary succession allows for decomposition of fire - damaged plants while secondary succession allows for the migration of new animals into the area.

Explanation:

Primary succession occurs in areas where there is no soil initially, like after a volcanic eruption. It starts with pioneer species that help establish soil over time. Secondary succession occurs in areas where soil is already present, such as after a forest - fire. It is faster as there are existing seeds and roots in the soil. Primary succession establishes soil while secondary succession allows for the recovery of the community after a disturbance.

Answer:

C. Primary succession establishes soil in the area while secondary succession allows for recovery of the community after a disturbance.
