A computational ecologist is tracking 45 species across 5 regional ecosystems. If each ecosystem has an average of 9 species and one ecosystem has 15 species, how many fewer species does that ecosystem have compared to the average?

**How A Computational Ecologist is Tracking 45 Species Across 5 Regional Ecosystems Holds Key Insights for Understanding Biodiversity Patterns** In an era of accelerating environmental change, a rising number of researchers are turning to computational tools to monitor biodiversity with precision. A computational ecologist is currently tracking 45 species distributed across five regional ecosystems—meaning, on average, nine species thrive per region. Yet one ecosystem stands out: with 15 species, it holds more than just occasional prominence, raising a clear mathematical question: how many fewer species does this ecosystem have than the average? This isn’t just a trivia—understanding these patterns reveals gaps, trends, and pressures shaping regional biodiversity. As climate patterns shift and habitats fragment across the U.S., tracking these numbers helps scientists model ecosystem resilience and anticipate ecological shifts in real time. ### Why A Computational Ecologist Is Tracking 45 Species Across 5 Regional Ecosystems Is Gaining Real Attention in the US
