What is the significance of biodiversity in an ecosystem?

Back

Biodiversity increases ecosystem resilience, productivity, and stability, allowing it to better withstand environmental changes.

What is the concept of carrying capacity?

Back

Carrying capacity is the maximum number of individuals of a species that an environment can sustainably support.
