Comparing with the real conditions in marine food chain,we can obtain the situation as shown in Figure 2.
According to Figure 2,we can find the calculated values is similar to the actual values,which prove the effectiveness of the differential equations in solving the actual situation.
The differential equations is fit for solving dynamic problems,describing the relationship of each variable quite accurately.We can use it in not only ecosystem but also a variety of situations,such as epidemics and economic growth.
Solving the differential equations is greatly difficult and it is not easy to obtain analytical solution,which restricts the application of differential equations.Therefore,in subsequent studies we should pay more attention to how to simplify the solution of differential equations and creating a more appropriate numerical method.
