DENDROLOGY

Detailed explanation-1: -Following a fire, early successional species disperse and establish first. This is followed by late-successional species. Species that are fire intolerant are those that are more flammable and are desolated by fire. More tolerant species are able to survive or disperse in the event of fire.

Detailed explanation-2: -The order of secondary succession is pioneer species, intermediate species, and finally climax community. The pioneer species are the first to colonize and include the producers like lichens and mosses. The intermediate species appear next and include shrubby plants and small trees.

Detailed explanation-3: -Secondary succession occurs after a disturbance such as a forest fire, where there is still some organic matter to allow new plants to grow.
