After a disturbance, how does an ecosystem typically return to a stable state?

• By human intervention

• It does not recover

• Through secondary succession

• Through primary succession

How does secondary succession differ from primary succession in terms of speed?

• It is slower because soil needs to form

• There is no difference in speed

• It depends on the type of ecosystem

• It is faster because soil and nutrients are already present

What condition allows secondary succession to occur more quickly than primary succession?

• Lower sunlight levels

• Absence of wildlife

• Presence of pre-formed soil

• Higher air quality
