What is an ecological disturbance?

• A temporary change in environmental conditions that causes a pronounced change in an ecosystem.

• A random event that has no impact on an ecosystem.

• A gradual change in environmental conditions that causes a pronounced change in an ecosystem.

• A permanent change in environmental conditions that causes a pronounced change in an ecosystem.

How do ecological disturbances affect ecosystems?

• Ecological disturbances always lead to an increase in biodiversity.

• Ecological disturbances only affect the physical environment, not species composition.

• Ecological disturbances have no impact on ecosystems.

• Ecological disturbances can disrupt the balance of species and alter the physical environment, leading to changes in biodiversity, species composition, and ecosystem functioning.

What is the role of ecological disturbances in succession?

• Ecological disturbances only occur after succession has already taken place.

• Ecological disturbances have no impact on succession.

• Ecological disturbances prevent the establishment of new species in an ecosystem.

• Ecological disturbances create opportunities for new species to colonize and establish themselves in an ecosystem.
