# One day you caught and marked 90 butterflies in a population. A week later, you returned to the population and caught 80 butterflies, including 16 that had been marked previously. What is the size of the butterfly population?a. 170b. 450c. 154d. 186e. 106

Summary Introduction

Introduction:

The population is composed of different species including all kinds of animals, plants, and others. Estimation of population size is done by using different techniques such as tagging, marking, and others.

Explanation

The explanation for the correct answer:

Option (b) is 450. The calculation to find the size of butterfly is given below:

N = Knk

Where, N is the size of the population, K is the butterflies caught when visited first, n is the butterflies that were initially marked, and k represents the butterflies that were previously marked.

K = 80n = 90k = 16

N =80×9016 = 450

Hence, option (b) is correct
