If the carrying capacity of the pond is 1,500 for this species, what is the expected population size after one year

450

Explanation:

A fish population of 250 in a pond has a maximum annual rate of increase of 0.8. If the carrying capacity of the pond is 1,500 for this species, what is the expected population size after one year?

The annual rate of increase in the population is 0.8 and the population is currently 250 in the pond, hence, the expected population size after one year can be calculated as thus:

Expected increase in the population = 0.8 x 250

     = 200

Expected population size after one year = 250 + 200

       = 450

Since a population of 450 has not exceeded the carrying capacity of the pond, the expected population size after one year is, therefore, 450.
