Verified step by step guidance1
Understand the concept of ecological succession, which is the process by which the structure of a biological community evolves over time. There are two main types: primary and secondary succession.
Primary succession occurs in lifeless areas where there is no soil, such as a newly formed volcanic island or a new marine area where a coral reef is developing. It starts from bare rock or water and involves the gradual establishment of a biological community.
Secondary succession occurs in areas where a disturbance has destroyed an existing community but left the soil intact, such as after a wildfire, hurricane, or human activity like farming. It involves the regrowth of a community that was previously established.
Analyze the given options: The development of a coral reef in a new marine area and the colonization of a newly formed volcanic island are examples of primary succession because they start from environments without soil.
The regrowth of a forest after a wildfire is an example of secondary succession because it involves the recovery of an ecosystem where the soil remains after the disturbance, allowing plants and animals to recolonize the area.
