Which one of the following statements is correct for secondary succession
It is similer to primary succession except that it has a relatively fast pace.
It begins on a bare rock
It occurs on a deforested site
It follows primary succession
Answers (1)
Secondary succession is one of two types of ecological succession of plant life. Unlike first primary succession, secondary succession is an event-triggered process (e.g., wildfires, harvests, hurricanes, etc.) that reduces already established ecosystems (e.g. forests or wheat fields) to smaller populations of species, so secondary succession occurs on existing land, while primary succession usually occurs where there is no land. Many factors affect secondary succession, such as trophic interactions, initial composition, and competition-colonization trade-offs. The factors controlling the increase in species abundance during succession are mainly determined by seed production and dispersal, microclimate; landscape structure (habitat patch size and distance from external seed sources); bulk density, pH and soil texture (sand and clay). Wildfires can lead to deforestation and further monitoring is currently underway.Therefore, the correct option is "it happened in a deforested place". Hence, option 3 is correct.
