Ecological Succession

____Succession occurs in areas where no previous ecosystem existed.

Which of the following is an example of primary succession?

• A forest regrowing after a wildfire

• Lichens colonizing a new lava flow

• A pond filling in and becoming meadow

• A cleared agricultural field turning into a forest

What is the main difference between primary and secondary succession?

• Primary Succession occurs in water, while secondary succession occurs on land

• Primary successions happens faster than secondary succession

• primary succession starts with bare rock, while secondary succession starts with soil

• secondary succession only occurs in desert ecosystems

Which event would most likely lead to secondary succession?

• A volcanic eruption covering an area in lava

• a glacier retreating and exposing bare rock

• A forest fire leaving behind soil and some surviving plants

• an asteroid impact wiping out most life in an area

What is the first species to colonize an area during primary succession?

• Grasses

• Trees

• Primary species like lichens and mosses

• Insects

Which of the following could cause an ecosystem to undergo succession?

• A hurricane destroying a coastal wetland

• A volcanic eruption creating a new island

• A landslide wiping out vegetation on a hillside

• All of the above

In ____ succession an ecosystem recovers after a disturbance like a wildfire, but soil remains intact.

What happens to biodiversity as succession progresses?

• It remains the same

• It decreases over time

• It increases as new species establish

• It disappears completely

Why does secondary succession occur faster than primary succession

• Secondary succession doesn't require plant life to start

• Soil is already present, allowing plants to grow more quickly

• secondary succession does not involve any environmental disturbances

• There are no pioneer species involved in secondary succession

How can human activities impact ecological succession?

• Deforestation can slow or prevent natural succession

• pollution can alter the types of species that colonize an area

• Urbanization can permanently disrupt succession processes

• All of the above
