The passage discusses population dynamics and growth. It states that the city of East Bumble had a population growth rate of 30 babies per year, as 45 babies were born and 15 people died in 2008, resulting in positive growth. Population growth can be exponential in ideal conditions but typically follows logistic growth, slowing down or stopping as resources become limited and the carrying capacity is reached.

1. Population Dynamics How populations change in any given area

2. How Populations Grow Geographic distribution – the area in which a population lives (its range)

5. In the city of East Bumble, if 45 babies are born in the year 2008 and 15 people died that same year, what was the growth rate for the city? Give answer in units of: _____ babies per year. Positive Growth rate = population increase Negative Growth rate = decrease Is the growth positive or negative?

9. Some limiting factors are not dependent on population density: (density-independent factors) - Unusual weather - Natural disasters - Some human activities Types of growth
