Final answer:
A platform with a healthy ecosystem benefits from diverse app availability, similar to how biodiversity in a biological ecosystem improves its function and stability.
Step-by-step explanation:
The question concerns the benefits offered by a platform with a healthy ecosystem. A healthy ecosystem provides several advantages, and among the options provided, diverse app availability is the benefit that corresponds closely to the concept of a rich and well-functioning ecosystem. Much like a biological ecosystem, where high biodiversity enhances ecosystem functions such as nutrient cycling and energy flow, a platform ecosystem benefits from the variety of applications catering to different user needs, stimulating innovation, and enhancing user experience. Additionally, as with ecosystems where species complement each other and more biodiverse areas are more stable and productive, a diversified app landscape on a platform typically results in increased resilience to changes and greater overall value to users.
