Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Primary succession is an ecological process that occurs in an environment in response to-
A
the destruction of existing vegetation.
B
erosion and weathering of rock.
C
a change exposing bare rock.
D
significant moisture in a short time.
Explanation: 

Detailed explanation-1: -Note: Primary Succession is an ecological succession that takes place after uninhabited, infertile habitat has been opened. Secondary succession happens when environmental or biological cause is affecting the primary succession property.

Detailed explanation-2: -Primary succession occurs when new land is formed or bare rock is exposed, providing a habitat that can be colonized for the first time. For example, primary succession may take place following the eruption of volcanoes, such as those on the Big Island of Hawaii.

Detailed explanation-3: -Primary succession happens when a new patch of land is created or exposed for the first time. This can happen, for example, when lava cools and creates new rocks, or when a glacier retreats and exposes rocks without any soil. During primary succession, organisms must start from scratch.

Detailed explanation-4: -Explanation: Primary succession occurs in an environment without previous life, or a barren habitat. Secondary succession occurs in an area that had previously been inhabited but experienced a disturbance, such as a wildfire. The newly created volcanic island has no previous life, and is made of rock, devoid of soil.

Detailed explanation-5: -primary succession, type of ecological succession (the evolution of a biological community’s ecological structure) in which plants and animals first colonize a barren, lifeless habitat.
