Answer:
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.
The expected population size after one year is 450
•Current population = 250
•Annual rate of increase = 0.8
•Expected population size =?
We'll begin by calculating the expected increase in the pond. This can be obtained as follow:
•Current population = 250
•Rate of increase = 0.8
•Expected increase =?
Expected increase = Current population × rate
Expected increase = 250 × 0.8
Expected increase = 200
•Current population = 250
•Expected increase = 200
•Expected population size =?
Expected population size = Current population + Expected increase
Expected population size = 250 + 200
Expected population size = 450
