A cladogram is a diagrammatic representation prepared by the evolutionary biologists to represent the relationship of the group of organism on Earth.
Nowadays The cladograms are prepared by comparing the molecular homology between the species called phylogeny. The cladogram is used by the scientists to study the relationship between the species and their origin as the cladogram is represented in the form of a tree with branches.
Competition for resources like food and space cause the growth rate to stop increasing, so the population levels off. This flat upper line on a growth curve is the carrying capacity. The carrying capacity (K) is the maximum population size that can be supported in a particular area without destroying the habitat.
