Succession Quiz

What is primary succession?

• The process of ecological succession that occurs in an area that has been previously colonized.

• The process of ecological succession that occurs in an aquatic environment.

• The process of ecological succession that occurs in a desert environment.

• The process of ecological succession that occurs in an area that has never been colonized before.

What are the primary factors that initiate primary succession?

• Presence of fertile soil

• Presence of mature vegetation

• Abundance of water

• Absence of soil or presence of bare rock or sand

Give an example of primary succession.

• Colonization of bare rock by lichens and mosses

• Growth of grasses and shrubs in a forest

• Formation of a coral reef

• Development of a mature forest after a wildfire

• Primary succession occurs in an area that has never been colonized before, while secondary succession occurs in an area that has not undergone a disturbance.

• Primary succession occurs in an area that has never been colonized before, while secondary succession occurs in an area that has been previously colonized but has undergone a disturbance.

What is the role of pioneer species in primary succession?

What is the role of climax community in succession?

• The role of climax community in succession is to maintain the balance of the ecosystem and provide habitat for a wide range of species.
