The biodiversity in an unstable environment is typically:

In an unstable environment, biodiversity is typically low due to harsh conditions that make it difficult for many species to survive. Unstable environments often include extreme temperatures, variable precipitation, or frequent disturbances such as storms or volcanic activity. These conditions create stress on the organisms that inhabit these areas, leading to challenges in finding food, shelter, and suitable habitats. As a result, only the most resilient species adapted to these harsh conditions can thrive.

Additionally, the lack of stability means that ecosystems frequently undergo changes that can wipe out species that are less adaptable. Consequently, the overall number of species present in these environments tends to be reduced, leading to diminished biodiversity. Thus, the lower biodiversity reflects the higher difficulty in sustaining life in such unstable and harsh settings.
