Compare Type I, II, and III survivorship curves on a logarithmic scale. See how different survival strategies result in characteristic curve shapes.
Survivorship curves compare how mortality is distributed across the lifespan of different species. Starting from 1000 individuals, the log scale allows all three types to be compared on one graph.
