Answer:
256
Explanation:
==>Trout population:
In 1992, we have 4
In 1993, we have 16
In 1994, we have 64
==>Required:
Population if trout in 1995
Thus, since we are told that the population growth is exponential, and looking at how the popuation increased from 1992 to 1994, we can see that the population increased yearly in the multiples of 4.
=> 4, 16, 64, ?
The next number in this series of exponential growth which represents the population in 1995 would be 256. I.e. (4)⁴ = 4*4*4*4 = 256
Population of trout in 1995 = 256
Moisture. The answer is moisture. Stratification is only possible due to the moisture being trapped with the seeds.
