Detailed explanation-1: -Insects and weedy plants (frequently from surrounding ecosystems) are often the first to recolonize the disturbed area, and these species are in turn replaced by hardier plants and animals. If the area remains undisturbed, the biological community’s ecological structure and species composition can stabilize.
Detailed explanation-2: -Ecology deals with the organisms and it’s environment.
Detailed explanation-3: -There are two major types of ecological succession: primary succession and secondary succession.
Detailed explanation-4: -Secondary succession Wildfires will burn most vegetation and kill animals unable to flee the area. Their nutrients, however, are returned to the ground in the form of ash. Since a disturbed area already has nutrient-rich soil, it can be recolonized much more quickly than the bare rock of primary succession.
Detailed explanation-5: -The 5 Stages of Succession are Nudation, Invasion, Competition and Co-action, Reaction, and Climax or Stabilization. At the same location, a succession of biotic communities naturally emerges one after another until the Climax stage is reached. In their early stages, biotic communities develop slowly.
