Can any1 tell me about population graphs?
The exponential graph does not take into account that eventually a population will reach a point where it has fully exploited its resources. It rises slowly at first, but then increasingly steeply, because as the population grows, there are more organisms reproducing. However, the rate of reproduction per organism is constant. If the graph is drawn on semi-log paper, it will be a straight line. The S-shaped curve considers that as a population fills its habitat, resources become scarce, and the population can only then grow slowly. The initial portion is very similar to the exponential curve. As the population fills its habitat, the rate of growth declines, until eventually, the population is stable at some maximum, called the carrying capacity. This is called the stationary phase. If populations grow quickly, they can exceed the carrying capacity, degrade the environment and experience swift decline. After the population crashes, the environment can rebound. This is illustrated in som
