Devyn BrewtonEnvironmental science 1301Test, Chapters 8,91.Population ecology _ is the branch of ecology that studies the structure and dynamics of population. Population density is the number of people living in each unit of area. People need to understand this because it can help you chose a home and help pick an eco friendly place3. Biotic potentialis the ability of a population of living species to increase under ideal environmental conditions – sufficient food supply, no predators, and a lack of disease. Carrying capacity - the number of people, other living organisms, or crops that a region can support without environmental degradation. J shaped growth curves, s- shaped, the exponential growth rate, and environmental resistance. All of these help us understand and manage our environment by telling us what we need to do to keep it nice. The exponential growth rate can tell people how much crops that area can support which is big if you live in a small rural area.
