Question

this bacterial population exhibited logistic growth over 24 hours. the growth rate of a population growing logistically increases with population size initially, when there is plenty of available space and resources for additional population growth. but the growth rate decreases as the populations size gets closer to the environments carrying capacity, when the environment has less space and fewer resources available for additional population growth. the size of a population growing logistically over time is modeled by an s - shaped growth curve that levels off as population size approaches the carrying capacity. bacterial population order the time periods. start with the period during which the population had the lowest growth rate. end with the period during which the population had the highest growth rate. lowest growth rate between hours 16 and 18 between hours 18 and 20 between hours 2 and 4 between hours 12 and 14 between hours 14 and 16

Explanation:

Step1: Understand growth - rate concept

The growth rate of a logistic - growing population is related to the slope of the population - time curve. A flatter slope means a lower growth rate, and a steeper slope means a higher growth rate.

Step2: Analyze each time - period

• Between hours 2 and 4: The curve is almost flat, so the growth rate is very low.
• Between hours 12 and 14: The curve starts to rise, but the slope is not very steep yet.
• Between hours 14 and 16: The slope is steeper than in the previous period.
• Between hours 16 and 18: The slope is even steeper, indicating a higher growth rate.
• Between hours 18 and 20: The slope is the steepest among these periods, so the growth rate is the highest.

Answer:

1. between hours 2 and 4
2. between hours 12 and 14
3. between hours 14 and 16
4. between hours 16 and 18
5. between hours 18 and 20
