What is the main difference between primary succession and secondary succession?
What is the main difference between primary succession and secondary succession?
- Primary succession occurs on bare surfaces like rock or sand, while secondary succession occurs after disturbances on soil. (correct)
- Primary succession is initiated by human activities, while secondary succession is a natural process.
- Primary succession is accelerated by pioneer species, while secondary succession is a slower process.
- Primary succession occurs in habitats with intact soil, while secondary succession occurs in habitats devoid of soil.
How do disturbance events impact ecosystem structure and function?
How do disturbance events impact ecosystem structure and function?
- Disturbances result in changes in species composition and habitat availability. (correct)
- Disturbances primarily benefit individual organisms and populations.
- Disturbance events lead to increased species diversity in an ecosystem.
- Disturbances only occur naturally and do not have anthropogenic causes.
What is the role of pioneer species in the process of succession?
What is the role of pioneer species in the process of succession?
- Pioneer species inhibit the development of soil in newly formed habitats.
- Pioneer species contribute to organic matter accumulation and promote weathering. (correct)
- Pioneer species negatively impact biodiversity in ecosystems.
- Pioneer species thrive only in already established ecosystems.
