= dt 0.1y-b. Consider the number of fish, y, in a certain population. The annual rate of change of a fish population is given by What is the meaning of 0.1y in this differential equation? dy There is an increase in the fish population each year, equal to 10% of the current population. O There is an increase in the fish population each year, equal to 1% of the current population. There is a decrease in the fish population each year due to harvesting, equal to 10% of the current fish population. O There is an increase in the fish population each year, equal to 50 fish each year.
