Question

for most populations, available resources are limited and restrict how much a population can grow. as a result, most populations cannot exhibit exponential growth forever. consider once again the population of bacteria growing in a petri dish. the petri dish initially contained nutrient agar for food, but no further nutrient agar was added later. the dish also had a lid that kept bacteria from immigrating into or emigrating out of the dish. this graph shows the growth of the population of bacteria over 24 hours. bacterial population select all the statements about this population that are supported by the graph. the population grew relatively slowly for the first 12 hours. the population grew relatively quickly between hours 14 and 18. the population size did not change much after hour 19. the population grew exponentially for all 24 hours.

Explanation:

• By observing the graph, for the first 12 hours, the population - size points are close to the x - axis with little change, indicating slow growth.
• Between 14 and 18 hours, the population - size points show a steep upward trend, indicating rapid growth.
• After hour 19, the population - size points are almost on a horizontal line, indicating little change.
• The population does not grow exponentially for all 24 hours as the growth is restricted by resources and levels off.

Answer:

The population grew relatively slowly for the first 12 hours.
The population grew relatively quickly between hours 14 and 18.
The population size did not change much after hour 19.
