Ecological Succession

Front

What are pioneer species?

Back

Pioneer species are the first organisms to colonize an area and begin the process of ecological succession.

Front

What is primary succession?

Back

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

Front

What is secondary succession?

Back

Secondary succession is the process of ecological succession that occurs in an area where soil exists but has been disturbed, such as after a forest fire.

Front

What role do lichens play in soil formation?

Back

Lichens contribute to soil formation by breaking down rocks and contributing organic material as they die.

Front

What is the impact of decomposition on soil?

Back

Decomposition of organisms enriches the soil with nutrients, aiding in the growth of plants.

Front

What is a disturbance in ecological terms?

Back

A disturbance is an event that disrupts ecosystem structure and function, leading to changes in species composition.

Front

How does succession affect biodiversity?

Back

Succession generally increases biodiversity as more species establish and interact over time.

Front

What is an example of a human-induced disturbance?

Back

An example of a human-induced disturbance is deforestation, where humans cut down trees in a region.

Front

What is the difference between primary and secondary succession in terms of speed?

Back

Secondary succession is generally faster than primary succession because soil and some organisms already exist.

Front

What is the role of volcanic eruptions in ecological succession?

Back

Volcanic eruptions can lead to primary succession by creating new land where no soil exists.
