Answer:
The renewal of a forest after a fire: The fire itself destroys a majority of different types of trees and plant life. Because seeds and roots and other plant and tree parts remain in and on the soil, gradually the plants and trees begin to grow again and eventually returns to the state of the original ecosystem.
The renewal of a crop after harvesting: Without new seeds being planted, the crop can regenerate the following year due to the plants and seeds that remained after harvesting.
A forest renews after logging: Lots of trees were chopped down by loggers to create building materials. Over time, trees grow in and the area returns to its previous state.
A volcanic eruption: In an area where a volcano erupts, lava may cause some damage to the plant and tree life. Over a span of years, however, if there was land that had been affected by the eruption but not necessarily covered in new volcanic rock, the seeds and plant parts and roots in the soil could renew.
On the island of Lawahii, several centuries ago, a fire erupted that caused the destruction of all plants and vegetation. Many years later, the plants and vegetation had grown back in, as the nutrients, seeds and soil remained.
Renewal after disease: A plant population can be very negatively affected by a variety of infectious plant diseases. If the entire population dies, but the soil and roots remain, it is possible for secondary succession to occur and for the population of those plants to to return.
A flood can ruin farmlands. However, because the soil remains after the waters recede, over the course of many years a natural secondary succession can occur and the vegetation that had previously grown there can grow again.
Plants can be very susceptible to attack from pests, particularly if there is an overpopulation of those pests. When this occurs, the plant population in one area can be completely destroyed. However, when the pest overpopulation is resolved, the plants are able to live again and thrive in the soil in which they previously had lived.
Potato scab is a tuber disease that grows on potatoes. If this disease affects a large amount of potatoes, the potatoes may not grow or may be harvested and thrown away. Over time, once the disease has been eradicated, healthy potatoes can grow again.
And also human activities can harm the environment and cause secondary secession.
