Answer: Active transport
Explanation:
Active transport can be defined as the process by which the molecules are transported against the concentration gradient by the help of energy.
The hormones like insulin are also transported by this process so that the hormone can reach to the place where it is required.
This is an energy consuming process because of sizeof molecule and the opposite of the concentration gradient.

Answer is 256.
In 1992 the trout population was 4. Thus, initial population of trout is 4. In 1993 it grew to (4)², that is 4×4 = 16, in 1994 it grew (4)³, that is 4×4×4 = 64. This shows the trout has grown exponentially. Therefore, the trout population will be (4)⁴, that is 4×4×4×4 = 256.
