Changing Ecosystems Flashcard

Front

What is primary succession?

Back

Primary succession is the process of ecological change that occurs in an area where no soil exists, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession is the process of ecological change that occurs in an area where an existing ecosystem has been disturbed but soil and some organisms still exist, such as after a forest fire.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a final stage of succession, where species composition remains relatively unchanged.

Front

What is ecological succession?

Back

Ecological succession is the gradual process of change and replacement in the species composition of a given area over time.

Front

What happens after lava covers the land?

Back

Primary succession occurs after lava covers the land, leading to the establishment of new ecosystems.

Front

What is the end product of aquatic succession?

Back

The end product of aquatic succession is often the formation of a new land ecosystem.

Front

Is ecological succession in new areas of land with little or no soil primary succession?

Back

True, ecological succession in new areas of land with little or no soil is called primary succession.

Front

What is the difference between primary and secondary succession?

Back

Primary succession occurs in lifeless areas without soil, while secondary succession occurs in areas where an existing ecosystem has been disturbed but soil remains.

Front

What role do pioneer species play in succession?

Back

Pioneer species are the first organisms to colonize a barren environment, initiating the process of ecological succession.

Front

Can a different type of biome emerge after secondary succession?

Back

Yes, a different type of biome can emerge after secondary succession, depending on the environmental conditions and species present.
