Answer:
According to what is observed in point A of the graph, referring to the population of beetles, there is no competition for resources.
Explanation:
The graph shows that a controlled population of beetles, where other individuals do not enter or leave, experiences <u>progressive growth over time</u>. This is because the population has sufficient resources to guarantee their development, the birth rate exceeds that of mortality and there is no competition for these resources.
The adequate amount of resources allows that, at point A, the carrying capacity has not been reached, a consequence of no competition among members of the same species, which ensures that the net population growth rate is maintained or even increase.
