Natural resources and the sustainability of the human population question in this activity, you’ll use the following computational simulation to analyze how management of natural resources affects the human population and a region’s biodiversity. the x-axis represents time and the y-axis represents population. part a the black curve on the graph represents exponential growth. the orange curve represents logistic growth. what difference do you notice between the two curves? part b the variable k in the logistic growth formula (orange) represents the carrying capacity of an ecosystem. use the sliders in the simulation to determine how the carrying capacity affects the population over time.
