What role do larger, different plants play in the process of succession after initial small plants?

Larger, different plants play a crucial role in the process of ecological succession, primarily by contributing to soil richness. As these larger plants grow, they contribute organic matter to the soil through processes such as leaf litter fall, root decomposition, and eventually the decay of the plant itself when it dies. This organic matter enriches the soil, increasing its nutrients and leading to further plant diversity. A richer soil supports a wider variety of plant species, which can sustain more complex ecosystems, ultimately promoting biodiversity.

These larger plants also help to stabilize the soil, reduce erosion, and improve water retention, creating a more conducive environment for other plant species to thrive. This dynamic is essential in succession, where initial small plants are succeeded by more complex plant communities, indicating a healthy progression towards a mature ecosystem.
