An ecosystem undergoes what is referred to as ecological succession in response to a disturbance. Ecological succession is the natural process in which a disturbed area is gradually taken over by a species or groups of species that were not there before.
Yes it is
A tornado destroys vegetation but leaves the soil and its contents largely intact, therefore we have secondary succession.

primary succession
The gradual change in the types of species that live in a community over time is known as ecological succession. This process typically starts with pioneer species and progresses towards a stable community through stages of primary and secondary succession. Factors like disturbances, competition, and environmental changes can influence the direction and rate of succession.
Pioneer species. These organisms are typically the first to establish themselves in a previously uninhabited or disturbed habitat, paving the way for other species to colonize the area. Pioneer species are often well-adapted to harsh conditions and play a crucial role in ecological succession.
Pioneer species are typically small herbivores. They are the first to colonize disturbed habitats and play a key role in the early stages of ecological succession by establishing a foothold for other species to follow.
Areas that have been severely disturbed, such as after a volcanic eruption or a wildfire, tend to undergo ecological succession at a faster rate. These areas have little to no vegetation and soil, allowing pioneer species to establish themselves quickly and kickstart the succession process.
The sequence of stages in ecological succession involves pioneer species, intermediate species, and climax community. Pioneer species colonize bare land, forming soil for other plants to grow. Intermediate species will colonize and establish the area, leading to a stable climax community that represents the endpoint of succession in that specific environment.
Pioneer species are the first plants or organisms to colonize a barren or disturbed area. They are important in succession because they play a key role in starting the process of ecological succession by breaking down rock or soil, making the area more habitable for other species to colonize and eventually leading to a diverse and stable ecosystem.
Without pioneer species, there would be no initial colonization or establishment of vegetation in barren habitats. This would disrupt the process of ecological succession, hindering the development of diverse and stable ecosystems in these areas. Pioneer species are essential for breaking down and preparing the environment for other plant and animal species to thrive.
Primary succession requires the presence of bare rock or soil, as well as pioneer species that can colonize and begin the process of ecological succession. These pioneer species often include lichens and mosses that can survive in harsh conditions and begin breaking down the rock or soil to create a suitable environment for other organisms.

A pioneer species. These are the first organisms to colonize a newly formed or disturbed habitat, playing a vital role in initiating ecological succession. Weeds are often fast-growing pioneer species that quickly establish themselves in disrupted environments.
This process is called ecological succession. It involves a series of predictable changes in the species composition and community structure of an ecosystem over time following a disturbance. It typically progresses from pioneer species, which can establish in harsh conditions, to more complex and stable communities.
