Front

How does biodiversity contribute to ecosystem resilience?

Back

Higher biodiversity increases ecosystem resilience, allowing it to better withstand environmental changes and disturbances.

Front

What is the significance of genetic diversity within a species?

Back

Genetic diversity allows populations to adapt to changing environments and helps prevent extinction.

Front

What role do keystone species play in their ecosystems?

Back

They help maintain the structure of an ecological community, influencing the types and numbers of various species.

Front

What are the potential impacts of invasive species on native ecosystems?

Back

Invasive species can outcompete native species for resources, disrupt food webs, and lead to declines or extinctions of native species.
