Biodiversity enhances ecosystem resilience, productivity, and stability.

Front

What is an example of a pioneer species in primary succession?

Back

Lichens and mosses are examples of pioneer species that colonize bare rock.

Front

How does ecological succession contribute to ecosystem stability?

Back

Ecological succession leads to increased biodiversity and complex interactions, which enhance stability.
