Answer:
Exponential growth
Explanation:
Exponential growth (sometimes called the log phase) is a type of population growth where bacteria are regularly doubling, uninhibited by any limitations such as nutrient availability. During exponential growth, the population will double at each interval of time, and therefore the rate of increase doubles at each interval.
Exponential growth is only part of the life of a bacterial population. Eventually, space/nutrient availability will drop and the waste products will rise, and the growth of the population will cease.
