The line graph illustrates the trends in wildlife populations of bears, dolphins, and whales over a five-year period from 2017 to 2022.
Overall, the graph depicts a significant decline in the bear and dolphin populations, while the whale population exhibited a consistent upward trajectory throughout the specified timeframe.
In 2017, the population of bears was recorded at 120 individuals; however, this number experienced a dramatic decline, plummeting to merely 20 by 2022. Dolphins exhibited more volatile dynamics, starting at 60 in 2017, escalating to 80 in 2018, then experiencing a sharp decrease to 40 in 2019, followed by fluctuations that ultimately saw the population fluctuate between 20 and 60 individuals until stabilizing at 60 in 2022.
Conversely, the whale population underwent an impressive surge, escalating from a modest 20 in 2017 to a substantial 180 in 2022. Following an initial dip to approximately 60 in 2018, the figures for whales rebounded, reaching 100 by 2019 and continuing to rise each subsequent year. This trajectory starkly contrasts with the trends observed in both the bear and dolphin populations, highlighting a significant shift in wildlife dynamics over the five-year period.
