Question

At present, growth of human population is represented in

• A. Lag phase
• B. Exponential phase
• C. Exponential phase almost terminating stationary phase
• D. Stationary phase

Answer 1

Answer: (B)

Exponential phase

Population growth occurs due to the availability of enough resources. Rapid reproduction, the decline in death rates, produces a net increase in the population size. Populations tend to grow exponentially as long as there are resources available. Most populations have the potential to expand at an exponential rate since reproduction is generally a multiplicative process. Thus, the correct answer is option B.
