A biologist is studying a population of frogs in a wetland. She counts 150 frogs and notes that 40% are green, 30% are brown, and the rest are yellow. How many yellow frogs are there?

**How Many Yellow Frogs Are in the Wetland? A Scientist Counts and Calculation Reveals the Answer** In an era where nature’s subtle rhythms draw growing curiosity, a practiced eye tracking a frog population offers more than just numbers. Recent fieldwork in a U.S. wetland reveals a structured count of 150 frogs, with 40% identified as green, 30% brown, and the remainder yellow—sparking interest in ecological patterns and population dynamics. This simple numeric puzzle reflects broader trends: safe habitat monitoring, species observation, and the quiet importance of biodiversity tracking. Understanding how these frogs thrive helps inform conservation, environmental health, and even climate adaptation insights, drawing attention from researchers and concerned naturalists alike. Why is a biologist studying a wetland’s frog population capturing quiet attention? With growing focus on ecosystem health amid climate shifts, frog counts provide vital data. Scientists use such numbers to assess habitat quality, detect changes in biodiversity, and monitor pollution or habitat loss—making frog population studies an essential part of environmental science. The structured breakdown of colors—green, brown, yellow—helps reveal patterns in species distribution, offering clues about life cycles, mating behaviors, and evolutionary adaptations relevant to wetland conservation. This context fuels fascination beyond casual viewers, connecting public curiosity with imperative scientific work. To determine how many yellow frogs are in the 150-count population, start with the known percentages. Forty percent of frogs are green, meaning 40% of 150 equals 60 frogs. Thirty percent are brown, equaling 0.3 × 150 = 45 frogs. Together, green and brown frogs total 60 + 45 = 105. Dividing the total count—150—by the combined 105 reveals the remainder: 150 − 105 = 45. These 45 frogs represent the yellow population, the final outcome of the count.
