Front

What is the significance of biodiversity in an ecosystem?

Back

Biodiversity increases resilience, stability, and productivity of ecosystems.

What is the role of decomposers in nutrient cycling?

Back

Decomposers break down dead organic matter, returning nutrients to the soil for use by producers.
