Ecosystems can recover after a natural disaster through a process called ecological succession. This process involves different stages where plant and animal species gradually repopulate the area and restore the balance of the ecosystem. Pioneer species, such as fast-growing plants, are usually the first to colonize the area. Over time, more complex and diverse species establish themselves, leading to the restoration of the ecosystem. Additionally, natural factors like soil nutrients, sunlight, and water availability also play a crucial role in the recovery process.
