The graph below shows, the population of seals, Whales and Dolphins in 2006, 2010, 2014, 2018. Write a reoport the university lecturer, and make conmparisions wherever necessary.
The given bar graph represents changes in the population of seals, whales and dolphins between the period of 2006-2018, the duration is divided into four parts with 4 years gap.
Overall, the population of seals fell and rose during the given period, while that of whales fluctuated, and dolphins climbed.
In 2006, the numbers of seals were around 42, but between 2006 and 2010, their population declined to approximately 28; thereafter, by 2014, their numbers increased to nearly 34, and further soared to about 42 by 2018.
Further, the numbers of whales experienced fluctuations between nearly 22 and around 25 in the given period. Initially, their numbers increased from around 22 to 24 by 2014, and then, there was a fall to about 22. Later, in the next 8 years their numbers did not change much.
Looking at the rest of the data, the population of dolphins experienced a surge from about 15 to almost 50. From 2006-2014, the rise was slow, but thereafter, the climb was swift.
