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

Generation# of bacteriatime min 3430min 4845min 5161hr 63275min 76490min min 92562hrs hrs , , ,5364hrs 18131, , , ,048,5765hrs 222,097, ,194, ,388,608

But can a population continue to grow at this rate? NO Limiting factors will control population growth Food shortages Lack of space Accumulation of own waste products Lack of other resources like oxygen, living space etc.
