Verified step by step guidance

Understand the concept of biodiversity: Biodiversity refers to the variety and variability of life forms within a given ecosystem, biome, or the entire Earth. It is crucial for ecosystem health and function.

Identify the benefits of biodiversity: Biodiversity contributes to ecosystem productivity, resilience, and stability. It ensures that ecosystems can recover from disturbances and adapt to changes.

Analyze the options provided: Consider each option and how it relates to the benefits of biodiversity. Improved resilience to environmental changes, increased ecosystem productivity, and enhanced stability of ecosystems are all recognized benefits.

Consider the concept of genetic variation: Genetic variation is a key component of biodiversity. It allows species to adapt to changing environments and contributes to the resilience and stability of ecosystems.

Determine which option is not a benefit: Decreased genetic variation is not a benefit of biodiversity. In fact, biodiversity aims to increase genetic variation, which supports the adaptability and survival of species.
