Detailed explanation-1: -A (J, S)-shaped curve describes the tendency of a population to grow without limit to its size. If a population’s death rate is (less, greater) than its birthrate, the popualtion will grow. (Food availability, Earthquake damage) would be a density-dependent limiting factor on the growth of a population.
Detailed explanation-2: -J curve can be defined as the j shaped growth curve that graphically represents a situation in a new environment where the population density of an organism increases at an exponential rate.
Detailed explanation-3: -Exponential growth As a result, the population growth rate increases with each new generation. Under this model, a population rapidly grows quite large, and continues to grow indefinitely: A line graph titled Exponential Growth showing population size over time.
Detailed explanation-4: -In logistic growth, population expansion decreases as resources become scarce, leveling off when the carrying capacity of the environment is reached, resulting in an S-shaped curve.
