Explanation:
Detailed explanation-1: -In an area where there is no soil, the process is called primary succession. In an area where soil already exists, such as an abandoned field or forest after a fire, the process is called secondary succession.
Detailed explanation-2: -So, the correct answer is ‘Secondary succession’.
Detailed explanation-3: -Ecological succession is the process by which the mix of species and habitat in an area changes over time. Gradually, these communities replace one another until a “climax community”-like a mature forest-is reached, or until a disturbance, like a fire, occurs.
Detailed explanation-4: -Once an ecosystem has reached a stable stage, it is called a climax community.
