An ecosystem model predicts that a fish population grows by 12% annually in a lake with no predation. If the population is 8,000 in 2022, what was it in 2020?

**Discover the Math Behind Population Growth — Understand Climate Resilience and Modeling** Why are so many US-based naturalists, environmental planners, and water resource managers examining how fish populations grow naturally in controlled conditions? Recent interest in sustainable ecosystem modeling has highlighted the power of mathematical prediction — especially when it comes to species thriving without predation or external interference. One classic example involves a 12% annual growth rate in a closed aquatic system. When a fish population reaches 8,000 in 2022, modeling backward reveals how quickly such systems can expand — suggesting strong natural resilience in ideal environments. Understanding this model connects science, conservation, and everyday curiosity about nature’s dynamics. --- ### Why a 12% Annual Growth Rate Works — But Why Does It Matter Now?
