Question

The population growth depicted in the graph can be best described as

• A. On day 1, the resources of the population limit its growth.
• B. On day 2, the birthrate per individual is greater than on day 1.
• C. On day 3, the population size is equal to K.
• D. On day 4, the curve is most similar an exponential growth curve.
• E. On day 5, the number of deaths approaches the number of births.

Answer 1

The correct option is E On day 5, the number of deaths approaches the number of births.

In the given graph which depicts population growth, you can find a growth curve which increases from Day 0 to 4.

It starts from lag phase, which shows the starting of growth. In this phase, the organism gets adjusted to the environment and is getting ready for growth.

Then comes the log phase or exponential phase where the growth rate is very rapid.

The last stage is a stationary phase on day 5 where the number of deaths = a number of births. In this way, the population at this stage remains constant and the population can be described more accurately.

Therefore, the correct answer is option E.
