The line graph presents data on the population trends of bears, dolphins and whales from 2017 to 2022.
Overall, the number of bears showed a significant and steady rise over the years, while dolphins experienced a sharp decline. Meanwhile, the population of whales fluctuated but remained relatively stable compared to the other two animals.
According to the graph, the population of bears rose steadily throughout the period. Starting at just 8 in 2017, it jumped to 54 in 2018 and nearly doubled to 93 by 2019. The growth continued as the numbers reached 116 in 2020, 137 in 2021, and peaked at 184 in 2022. Meanwhile, the dolphin population experienced the opposite trend, plummeting from 150 in 2017 to just 1 in 2022, with the sharpest drop occurring after 2018.
After that, the whale population displayed fluctuations. It started at 80 in 2017, dipped to 54 in 2018, and reached its highest point at 100 in 2019. However, it then declined gradually to 76 in 2020, rose slightly to 93 in 2021, and fell to 72 by 2022. Overall, the graph highlights contrasting trends: bears saw continuous growth, dolphins faced a rapid decline, and whales remained relatively stable with minor variations.
