Under ideal conditions, the per capita birth rate in a population of isopods is 0.12 offspring per day, and the per capita death rate is 0.04 offspring per day.If there are 700 individuals in the population, the population will produce how many isopods per day?
A) 8
B) 28
C) 56
D) 70
E) 84

To calculate the population growth rate, we need to subtract the death rate from the birth rate:

growth rate = birth rate - death rate
growth rate = 0.12 - 0.04
growth rate = 0.08

This means that, on average, each isopod in the population contributes a growth rate of 0.08 offspring per day.

To calculate the total number of offspring produced by the population per day, we simply multiply the growth rate by the number of individuals in the population:

total offspring per day = growth rate × number of individuals
total offspring per day = 0.08 × 700
total offspring per day = 56

Therefore, the population will produce 56 isopods per day. The best choice is C.
