Question
Whiteside and Ward also examined the carbon isotope ratios in the sediment over time. In particular they note certain intervals of "chaotic carbon" intervals: these are interpreted as occasions when biodiversity overall was greatly reduced, and ecosystems were highly unstable. In the plot below, the level of ammonoid diversity is shown on the left and the carbon isotope values on the right. This plot shows the entire Triassic Period: "upper Changh" is the very end of the Permian, "Hettangian" is the very beginning of the Jurassic, and everything in between is Triassic Diversity residuals -30-10 10 30 50 lower Sinem 201.3 Ma POOR DAT Norian Carbon isotopic stability 8) Is there any association between chaotic carbon and the extinction, or are they not correlated?

(8) ANSWER:-
Yes, there is obviously an association between Chaotic Carbon & Extinction.
EXPLANATION:--
According to the given plot we can interpret that in the Chaotic Carbon intervals (the red zone towards the right side of plot), the graph of Ammonoid genetic diversity declined abruptly and reached near zero. And, when the Chaotic Carbon Zone ended the graph of Ammonoid genetic diversity again rose.
