The line graph illustrates the population of turtles in India, showing trends for various species between 1980 and 2012.
Overall, the population of leatherback turtles experienced a significant decline, while the Olive Ridley turtles saw a general increase over the years, despite some fluctuations. The population of green turtles exhibited notable variations, although it experienced a slight overall decrease by the end of the period. Across all species, the total turtle population remained relatively stable with some fluctuations, indicating both positive and negative shifts over the years.
In greater detail, the population index for leatherback turtles began at 100 units in 1980 but dropped consistently throughout the period. By 2012, their index had declined sharply to approximately 60 units, marking the most severe drop among all turtle species. In contrast, Olive Ridley turtles demonstrated steady growth, with their population reaching over 120 units by 1997. However, this upward trend reversed slightly towards 2012, with the index falling slightly below 120 units.
The green turtle population showed more volatile changes throughout the timeline. Initially, the index fluctuated significantly, but by 2012, the index for green turtles settled slightly above 90 units, reflecting a mild decrease over the years. As for the overall turtle population in India, it remained relatively stable around the 100-unit mark, though the trend was characterized by several ups and downs across the years. This stability contrasts with the sharp changes observed in individual turtle species.

The line graph provides insights into the population of turtles in India across different species from 1980 to 2012.
Overall, the most notable trend is the sharp decline in the population of leatherback turtles, whereas Olive Ridley turtles demonstrated significant growth during the initial phase of the period, despite fluctuations later. Meanwhile, the population of green turtles exhibited some irregular patterns over the years, ending with a minor decrease by 2012. The total population of all turtle species combined experienced slight variations, but it largely maintained stability over the observed years.
In more specific terms, the leatherback turtles began with an index of 100 in 1980 but showed a continuous decline, eventually dropping to nearly 60 units by the end of the period. This decrease was the most severe among the species analyzed. On the other hand, Olive Ridley turtles displayed a marked increase, particularly during the first half of the timeline, peaking at over 120 units in 1997, before experiencing slight fluctuations that brought their index below 120 units by 2012.
The green turtles followed a more volatile path, with their population index fluctuating considerably between 1980 and 2000. However, by 2012, the population of green turtles saw a marginal drop, settling just above 90 units. Meanwhile, the combined population of turtles in India showed no drastic change, hovering close to the baseline of 100 units throughout the period, with occasional fluctuations reflecting the changes within individual species.
Model Answer 3
The line graph provides information about the population of turtles in India across different species from 1980 to 2012, presenting changes in their population indices over time.
A glance at the graph reveals that the leatherback turtles witnessed a considerable decline in their population throughout the period, while the Olive Ridley turtles initially experienced substantial growth, though not without subsequent fluctuations. The green turtles exhibited a more inconsistent pattern, with their population varying over time before experiencing a slight decrease. In contrast, the overall population of turtles in India remained fairly stable, with some minor variations observed across the years.
Looking more closely at the data, the leatherback turtles started the period with an index of 100, but their numbers dropped consistently over the years, reaching a low of approximately 60 units by 2012. This species saw the most pronounced reduction in population among all the turtle species analyzed. Meanwhile, the Olive Ridley turtles demonstrated a rising trend, with their population index peaking around 1997, exceeding 120 units, although it declined slightly towards the end of the period.
The green turtles, however, displayed a more erratic trajectory. Their population index fluctuated throughout the years, and by 2012, it settled at just above 90 units, marking a modest decline from the starting point. The combined population of turtles in India, while showing occasional fluctuations, largely remained close to 100 units, indicating that the aggregate population stayed relatively steady over the entire period.
