To prevent soil erosion permanently
B
To establish a stable ecosystem immediately

검증된 단계별 안내1
Understand the concept of primary succession: Primary succession occurs in lifeless areas where there is no soil, such as after a volcanic eruption or on a newly formed sand dune.
Identify the role of pioneer species: Pioneer species are the first organisms to colonize a barren environment. They are typically hardy species that can withstand harsh conditions.
Recognize how pioneer species modify the environment: These species contribute to soil formation by breaking down rocks and accumulating organic material as they die and decompose.
Explain the impact on the environment: By modifying the environment, pioneer species create conditions that are more favorable for other species to colonize, such as the development of soil that can support plant life.
Conclude the role of pioneer species: The primary role of pioneer species in primary succession is to modify the environment, making it more suitable for subsequent species, thereby facilitating the establishment of a more complex ecosystem over time.
