Logistic growth occurs during a population growth when the resources are limiting. During logistic growth sigmoid (S-shaped) growth curve is produced when population size is placed over time.
In logistic growth first the population increases slowly then after some time it increase on the logarithmic phase until it levels off near the maximum carrying capacity due to environmental resistance. Beyond this maximum carrying capacity growth rate does not increase and becomes constant.
This generates an s-shaped curve called a sigmoid curve which shows the logistic growth. So the correct answer is c.
The circulatory system is the transport system for endocrine information. While the nervous system uses neurons, the endocrine chemicals and hormones must circulate through the body via blood vessels. Many glands in your body secrete hormones into the blood.
