Effects of Additional Foods to Predators on Nutrient-Consumer-Predator Food Chain Model

Figure 7

This figure illustrates that the smooth line indicates the stability and the dashed (-) line indicates the instability of the system (3) with respect to quality of additional food 𝛼 for 𝑁⁰=2.5, 𝑎=0.26, 𝛼₁=1, 𝛼₂=0.5, 𝛾₁=0.2, 𝛾₂=0.15, 𝛽=0.4, 𝛽₁=0.2, 𝑑₁=0.215, 𝑑₂=0.107, 𝜔=0.5, and 𝜉=1.
