Dead leaves accumulate on the ground in a forest at a rate of 3 grams per sq cm per year. At the same time, leaves decompose at a rate of 75% per unit weight per year. Let the weight of the leaves per sq cm at time t in years be L.

a. Write a differential equation for L

b. For what value of L is L =0?

c. What happens to L if it takes the value of L you found in problem b?
