J-shape curve
J-shape curve is a curve that shows the population density of an organisms as they increase rapidly in a logarithmic or exponential form but abruptly stops due to environmental resistance. Thus, the population rate is largely determined by the biotic potentials and size of the population. However, exponential growth produces J-shaped curve.
Biogeography is the study of geographical distribution of fossils, various species (plants and animals) and ecosystems throughout geological time and space
