Question

in a pond There were 50 fishes last year and through reproduction, 10 new fishes are added, taking the current population to 60, what will be the birth rate per fish per year ? ​

Answer 1

Answer:

no. of fish last year : 50

additional :10

current no. : 60

therefore, current no. - no. of fish last yr

= 60-50

= 10

therefore, birth rate is 10% per year .

Answer 2

The birth rate in the pond per year will be 0.2.

Step-by-step explanation:

Given:

Current pond population = 60

Number of new fishes added= 10

population prior to reproduction = 50

To find: birth rate/ new fish

birth rate equation = new addition to current population/ population before birth

birth rate formula= 10/50 =  0.2

Thus, the birth rate in the pond per year will be 0.2.
