B) the number of organisms dying within any given time period. C) the percentage of organisms dying within any given time period. D) calculated by dividing N_x by N₀, or the number of individuals surviving by the starting number. E) calculated by dividing N₀by N_x, or the starting number of individuals by the number surviving.
