**Educational Website Text:****Survivorship Curves Analysis**Use the survivorship curves in Figure 52.1 to answer the following questions.**Figure 52.1: Survivorship Curves**This figure includes five survivorship curves (A, B, C, D, and E) plotted on a logarithmic scale. The y-axis represents the number of survivors (log scale), and the x-axis represents relative age.- **Curve A**: This curve depicts high survivorship during early and middle life, followed by a steep decline in older age. Commonly associated with species that invest heavily in offspring care. - **Curve B**: This curve shows a steady decline in survivorship throughout the lifespan. Organisms with this curve experience constant mortality rates.- **Curve C**: This curve has a convex shape, indicating that most individuals survive to middle age but then face increased mortality.- **Curve D**: Stepped appearance suggesting periods of high mortality followed by periods of low mortality.- **Curve E**: This curve illustrates very high mortality rates early in life, with survivorship stabilizing for those who make it past a certain age. This pattern is typical for species with many offspring and little parental care.**Question:**Which curve best describes survivorship in oysters?[Answer Box]

A survivorship curve is a graphical presentation of the number of survivors of a given species over the span of their typical lives (over a period of time). Hence it shows at which relative age the mortality is high in those species and at which age the survivorship is better. In Oysters, like in many marine animals, the number of offsprings produced is very high, but also there is a high mortality rate in the early stages of life as can be seen with a sharp decline of a graph showing poor survivorship. But once the oyster has grown these early stages, then survivorship stabilizes with a fewer number of survivors. Hence the Oysters show a Type III survivorship curve. Also, this curve is seen where parental care of offsprings in minimal or altogether missing.Hence, the blank can be filled with Curve E.
