Question

glacier melting is an example of primary or secondary succession because soil is present or no soil is present

Answer 1

Glacier melting is an example of **primary succession** because it creates a new habitat where soil is not initially present. As glaciers recede, they expose bare rock, which eventually leads to the colonization of pioneer species, such as lichens and mosses. Over time, as these organisms die and decompose, they contribute to the formation of soil, allowing for further ecological development. In contrast, secondary succession occurs in areas where soil is already present, such as after a forest fire or agricultural land abandonment.
