The given graph shows the difference in number of population for 3 wildlife species across 6 years from 2011 – 2016.
It is apparent that there is a lot of disparity among the different species. They each start off at different numbers and while some increase in number across the years, some decrease in number.
The dolphins started off in 2011 with the highest number at 150000, reduced gradually and then finished off with the lowest number of 0 in 2016. Meanwhile, the bears began with the lowesr number of about 8000 and grew steadily and slowly across the years and reached a total of about 180000 in 2026. The less significant species is the whales as the began and ended with almost the same number, with about 80000 for the former and about 70000 for the later.
Between 2012 and 2013, the 3 species had a period in which they were all at the same population of about 60000. The bears and whales increased in number after this, but the dolphins decreased in number.
