Here is your guide response!

The first type of population grown is exponential growth. Exponential population growth is when the population grows at a constant rate over time. It is not affected or limited by competition, lack of resources, disease, etc. (Otherwise, 2012). Essentially, the only thing that controls how fast or slow the population grows is the birth rate. (Otherwise, 2012). The second type of population growth is logistic population growth. It reflects more of a reality, as there are few populations in which limited resources, disease, etc. is not a factor. As the number of individual organisms in the population increases, resources become important as conditions become crowded. (Britannica, 2012). In a environment where these conditions exist, populations show logistic growth as the environment reaches its carrying capacity. (Britannica, 2012). Human population grown has changed across time, based on numerous factors including disease, birth rate, economic conditions, etc. (Simon, Reece & Dickey, 2010) It also changes depending on the part of the world that is being studied. However, overall, the human population is growing exponentially, although it has slowed over the past century. (Simon, Reece & Dickey, 2010) However, population grown projections indicate that the environment is near its carrying capacity, and that food production must dramatically increase to keep up with the growing population. (Simon, Reece & Dickey, 2010).
