Review Test 3: Ecological Succession

Front

What is ecological succession?

Back

Ecological succession is the process by which ecosystems change and develop over time, involving a series of stages that lead to a stable community.

Front

What are the two main types of ecological succession?

Back

The two main types of ecological succession are primary succession (starting from bare rock or lifeless areas) and secondary succession (following disturbances in an existing ecosystem).

Front

What is a pioneer species?

Back

Pioneer species are the first organisms to colonize previously uninhabited or disturbed environments, initiating the process of ecological succession.

Front

What role do weeds play in ecological succession?

Back

Weeds often act as pioneer species, restructuring habitats and allowing hardier plants to survive by competing for resources.

Front

What is the primary consequence of deforestation in tropical rainforests?

Back

Increased carbon dioxide levels in the atmosphere.

Front

What process occurs for a forest ecosystem to recover after a wildfire?

Back

Succession.

Front

What happens after lava from a volcanic eruption cools?

Back

New plants and animals begin to populate the newly-formed surface through the process of succession.

Front

What is the impact of regular fires on a pine forest?

Back

If fires stop, oak communities that do not tolerate fire will likely take over the pine forest.

Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity contributes to ecosystem resilience, stability, and the ability to recover from disturbances.

Front

How does ecological succession contribute to habitat restoration?

Back

Ecological succession helps restore habitats by gradually reintroducing species and rebuilding the ecosystem structure.
