These beetles have a uniform distribution. In year 1, how many beetles are there per hectare? How many beetles per hectare were there in the year the beetles reached carrying capacity? Round up or down to the nearest whole number, if necessary.

In year 1, the population was 11,500 spread over 115 hectares.

The number of beetles per hectare is  beetles.

By year 6, when the beetles reached the carrying capacity, the number of beetles per hectare is  beetles.

Explanation:

In year 1, the population was 11,500 spread over 115 hectares.

The number of beetles per hectare is 11,500/115= 100 beetles.

By year 6, when the beetles reached the carrying capacity, the number of beetles per hectare is 14,677/115 = 128  beetles.

Explanation:

This is the sample answer from PLATO

well, that's easy; the answer's c, "it reduces contamination of the water and substrate of the estuary."
