Secondary Succession
Explanation:
A secondary succession is usually defined as a type of ecological succession, where the new floras and faunas are resettled after the occurrence of flood, forest fire, earthquake or any other disaster that destroys the previously existed ecosystem.
This type of succession is possible to occur because the essential nutrients that are required for the survival of organisms occurring in a particular area are not completely destroyed.
The secondary succession takes place at a much faster rate compared to the primary succession.
Thus, in the given condition, the secondary succession will occur after the occurrence of a massive forest fire.

Photosphere is the surface of the sun that is visible to the eyes. It is believed to be one of the coolest part of the sun. The dark spots on the photosphere are known as the sunspots. Sunspots are usually visible in groups and are temporary because they only come and go. Magnetic fields are believed to have been involved in the occurence of the sunspots. Solar prominences are sometimes associated with the occurence of sunspots. They are active events that occur when sheets of gases are released from the active regions.
