Answer:
Disturbances can leave legacies or traces in the landscape, vegetation or soils of variable duration. They can alter the ecological succession.
Explanation:
Ecological succession is the evolution that occurs naturally, producing a dynamic ecosystem.
A disturbance is any discrete and external event that alters an ecosystem, community or population, which changes the availability of resources or physical environment.
Agents of natural disturbances:
• Winds (storms, hurricanes, tornadoes)
• Tree falls
• Moving water (floods)
• Landslides
• Frost
• Droughts
• Fires
• Animals (grazing, pests)
Human disturbances:
• Agriculture and grazing
• Mining
• Pollution
• Irradiation
