Question

when can diseases, starvation, and overcrowding impact the human population the most? when the population is sparse, very spread out, and under carrying capacity when the population is very close together and is over carrying capacity population levels have no impact on the spread of disease, overcrowding, and starvation.

Explanation:

To determine when diseases, starvation, and overcrowding impact human population most, we analyze each option:

• The first option (sparse, spread out, under carrying capacity) is incorrect. Sparse populations limit disease spread, and under carrying capacity means resources are sufficient, so starvation/overcrowding are less likely.
• The second option (very close together, over carrying capacity) is correct. Close proximity facilitates disease spread, and exceeding carrying capacity (the maximum population an environment can support) leads to resource shortages, causing starvation and overcrowding.
• The third option is incorrect as population levels clearly impact disease spread, overcrowding, and resource availability (thus starvation).

Answer:

B. when the population is very close together and is over carrying capacity (assuming the options are labeled A, B, C with A being the first, B the second, C the third)
