Answer

Explanation:

Step1: Analyze bass population

In year 1, bass population is 58, in year 2 it is 40 and in year 3 it is 31. Since 58>40>31, the number of bass decreased over time.

Step2: Analyze catfish population

In year 1, catfish population is 57, in year 2 it is 76 and in year 3 it is 80. Since 57<76<80, the number of catfish increased over time.

Step3: Analyze total fish population

Total population in year 1: 77 + 57+58 = 192. Total population in year 2: 83 + 76+40 = 199. Total population in year 3: 92+80 + 31=203. Since 192<199<203, the fish population increased over time.

Answer:

  • The number of bass decreased over time.
  • The number of catfish increased over time.
