What is succession?

• The first species to populate an area.

• Is the same of intereaction

• Is Disruption to the physical or biological components.

• The series of predictable changes that occur in a community over time.

Plant life starting to grow on a volcano

• primary succession

• secondary succession

• tertiary succession

• variable succession

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 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 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 study of animal behavior in their natural habitats

Answer explanation

Ecological succession is the process by which the structure of a biological community evolves over time.

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.
