Forest Succession

What is secondary succession caused by?

• Glacier receding

• Fire, Tornado, Flood, Human Activities

• Volcanic Eruption

• New Island Forming

What are the first organisms to colonize an area?

• Climax Species

• Shade Tolerant Trees

• Trees and Shrubs

• Pioneer Species

Which of these is an example of a pioneer plant living where no soil exists?

• Moss

• Alder shrubs

• Paper Birch Trees

• Raspberry Plants

What is a common characteristic among pioneer species?

• roots that break apart rocks

• long thick roots

• exposed surface roots

• soak up water quickly

How does soil development differ between primary and secondary succession?

• Soil develops faster in primary succession.

• Soil is already present in secondary succession.

• Soil is not important in either type of succession.

• Soil develops at the same rate in both types.

What is the main difference between primary and secondary succession?

• Primary succession occurs in areas with existing soil, while secondary succession starts on bare rock.

• Primary succession starts on bare rock, while secondary succession occurs in areas with existing soil.

• Primary succession involves only plants, while secondary succession involves animals.

• Primary succession is faster than secondary succession.

What is ecological succession?

• The process by which the structure of a biological community evolves over time

• The study of how living organisms interact with each other

• The process of recycling nutrients in an ecosystem

• The migration of species from one habitat to another

Which of the following best describes the difference between primary and secondary succession?

• Primary succession occurs faster than secondary succession

• Secondary succession starts on soil, while primary succession starts on bare rock

• Primary succession can only occur in water, while secondary succession occurs on land

• Secondary succession involves the introduction of new species, while primary does not

Why is ecological succession important for ecosystems?

• It decreases biodiversity over time.

• It leads to the destruction of habitats.

• It helps ecosystems recover from disturbances.

• It ensures that pioneer species dominate the ecosystem.

Compare the roles of pioneer species in primary and secondary succession.

• They are more important in secondary succession.

• They are equally important in both types of succession.
