Question

Which factor can cause secondary succession?

Answer 1

Answer: a) clear cutting

Explanation:

An ecological succession is a change in the biotic community of an ecosystem with respect to changes occurring in the abiotic factors (non-living) such as sunlight, water, climate and climate in the course of time until the ecosystem attains stability. A secondary succession occurs in a region which was previously colonized by the living species but disturbed by human induced or natural calamity.

A secondary succession will occur in clear cutting because of the fact that some of the precursors such as seeds, stem stocks and roots can give birth to new plants and may help in recolonization of the region.

Answer 2

'm going to say clear cutting because clear cutting reduces a ecosystem/population of species that has been there for a while or long while. With secondary succession it is a process that is triggered by an event such as clear cutting or natural disasters.

Hopefully this helped and good luck.
