1. Even at a very low r, a population can eventually show a j-shaped growth curve. Why? Why can’t real populations grow exponentially?
Homework Answers
r is biotic potential which is defined as reproduction capacity of organisms without restriction. Even if biotic potential is less , carrying capacity of that species could be effected by disease, competition predation etc .
Resources are always limited and no species could grow exponentially.

Select the statements that explain why very small and very large populations experience slow population growth under the logistic growth model. 1- Small populations have fewer individuals capable of producing offspring. 2- Limited resources are shared among many individuals in very large populations. 3- The intrinsic growth rate is higher when populations contain many individuals. 4- The carrying capacity is larger for populations that contain very few individuals.

- ap-bp? This equation is known as the logistic law of population growth and the numbers a, b are called the vital coefficients of the population. It was first introduced in 1837 by the Dutch mathematical-biologist Verhulst. Now, the constant b, in general, will be very small compared to a, so that if p is not too large then the term - bp will be negligible compared to ap and the population will grow exponentially. However, when p is very...
