1. Properties of populations Growth patterns Mortality patterns Age structure Density dispersion A population is a group of organisms of the same species living in the same place at the same time Read chapter 43 Pages 776 - 789

2. The growth rate of a population is the increase in the number of individuals over time. Exponential growth is when the number of individuals grows at a constant rate. Growing bacteria in a lab is a good example
