1. Types of Population Growth Vocabulary Exponential growth There are two types of population growth 1.Exponential growth a)Under ideal conditions with unlimited resources, a population will grow exponentially. b)The graph has a J-shape curve. c)Exponential growth occurs when the individuals in a population reproduce at a constant rate. d)No limits on growth

2. Exponential Growth

3. Agriculture begins Plowing and irrigation Bubonic plague Industrial Revolution begins

4. Vocabulary Logistic growth Carrying capacity 2.Logistic growth a)As resources become less available, the growth of a population slows or stops (limited resources). b)The graph has an S-shape curve. c)Population growth slows or stops at carrying capacity d)The largest number of individuals that a given environment can support is called carrying capacity.
