What is the primary 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 after a volcanic eruption

• Secondary succession leads to a climax community, while primary succession does not

Answer explanation

The primary difference between primary and secondary succession is that secondary succession starts on soil, while primary succession starts on bare rock.

Why is primary succession slower than secondary succession?

• Because it starts on bare rock where soil must first be created

• Because it involves larger animals

• Because it occurs after a disturbance

• Because it ends with a climax community

Answer explanation

Primary succession is slower than secondary succession because it starts on bare rock where soil must first be created, which is a time-consuming process.

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

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.

How does secondary succession differ from primary succession?

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

• Secondary succession is faster because soil is already present.

• Primary succession can only occur after a volcanic eruption.

• Secondary succession leads to a less diverse ecosystem.
