Front

What is the first type of organism to appear during primary succession?

Back

Pioneer species

Front

How does secondary succession differ from primary succession?

Back

Secondary succession starts where soil already exists.

Front

Which event is most likely to lead to primary succession? A wildfire in a forest, A hurricane flooding a coastline, A volcanic eruption creating new land, A forest being cleared for farming

Back

A volcanic eruption creating new land

Front

What do pioneer species do in primary succession?

Back

Create soil for other plants to grow

Front

During primary succession, what increases over time?

Back

Soil quality and plant diversity

Front

Which is a similarity between primary and secondary succession?

Back

Both occur after an ecosystem disturbance.

Front

Which disturbance would lead to secondary succession? Options: A volcanic eruption covering land with lava, A flood damaging a forest, A glacier retreating and exposing bare rock, An earthquake lifting ocean sediment to the surface

Back

A flood damaging a forest

Front

What factor allows secondary succession to happen faster than primary succession?

Back

Presence of soil

Front

What happens to species diversity during secondary succession?

Back

It increases over time.

Front

In secondary succession, which plants are likely to grow first?

Back

Small grasses and shrubs
