2.5 Succession FLASHCARD

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 are pioneer species?

Back

Pioneer species are the first organisms to colonize previously disrupted or damaged ecosystems, helping to create soil and establish a habitat for other species.

Front

What is primary succession?

Back

Primary succession occurs in lifeless areas where there is no soil, such as after a volcanic eruption or glacier retreat.

Front

What is secondary succession?

Back

Secondary succession occurs in areas where a disturbance has destroyed an existing ecosystem but left the soil intact, such as after a forest fire.

Front

What is the order of plant growth after a volcanic eruption?

Back

Lichens → Grasses → Shrubs → Trees.

Front

What is the main difference between primary and secondary succession?

Back

Primary succession begins without soil, while secondary succession begins with soil.

Front

What role do lichens play in succession?

Back

Lichens help to break down rocks and create soil, making it possible for other plants to grow.

Front

What is the significance of soil in ecological succession?

Back

Soil provides essential nutrients and a medium for plant roots, facilitating the growth of more complex plant communities.

Front

What is a climax community?

Back

A climax community is a stable and mature ecological community that has reached a steady state through the process of succession.

Front

What is the process of pond succession?

Back

Pond succession is the gradual process where a pond evolves into a terrestrial ecosystem, often starting with algae and leading to a forest.
