Is a glacier an example of primary succession?

What succession begins on bare rock after glaciers have passed?

On newly formed volcanic islands, what type of succession starts on bare rock? There is a primary succession.

What is the first stage in primary succession?

How primary and secondary takes place in the ecosystem?

There are a series of community changes which occur on a completely new habitat. There is a newly quarried rock face. Secondary succession is a series of community changes that occur on a previously colonized area.

Plants colonize and develop into communities as the land is exposed to the elements. The process of primary plant succession has been studied in Glacier Bay for 100 years, which is the longest study of its kind anywhere in the world.

What is a climax community ecological succession?

An ecological community in which populations of plants and animals are in balance with each other and the environment. A climax community is the last stage of succession and can be destroyed by fire or interference.
