Succession Day 2

When predictable changes occur in a community over time, it is called:

• evolution

• succession

• biodiversification

• natural selection

How is primary succession characterized?

• No soil remaining after a disturbance

• Soil remaining after a disturbance

• Small plants remaining after a disturbance

• Large hardwood trees remaining after a disturbance

How is secondary succession characterized?

• No soil remaining after a disturbance

• Soil remaining after a disturbance

• Small plants remaining after a disturbance

• Large hardwood trees remaining after a disturbance

What are examples of primary succession (choose all answers that apply.)

• Volcanic Eruption

• Tornado

• Glacier Melting to Expose Rock

• Deforestation

• Wildfire

What are examples of primary succession (choose all answers that apply.)

• Volcanic Eruption

• Tornado

• Glacier Melting to Expose Rock

• Deforestation

• Wildfire

What are examples of pioneer species?

• Humans and other Great Apes

• Common forest animals such as deer, squirrels, and raccoons

• Lichens and Mosses

• Grasses, trees, and shrubs

Why are pioneer species so important?

• They are the best at discovering new places

• They are the first species to live in an area after a disruption in the ecosystem

• They are able to survive most disruptions in ecosystems

• They are the first species discovered in their taxonomic genus

What is the final stage in succession called when the community finally reaches full growth after a disruption?

• Peak Performance

• Developed Ecosystem

• Climax Community

• Ecological Diversification

Would this disturbance lead to primary or secondary succession?

• primary

• secondary

Would this disturbance lead to primary or secondary succession?

• primary

• secondary
