Feedback mechanisms, such as those driven by supernovae and active galactic nuclei, play a central role in regulating star formation and shaping the properties of galaxies. However, quantifying the impact and efficiency of these feedback processes remains an ongoing challenge in astrophysics. In this study, we use the EAGLE suite of cosmological hydrodynamical simulations to investigate the effects of implementing various feedback models on the formation and evolution of model galaxies. We focus on the analysis of effective yields, testing their capability to provide insight into the impact of feedback processes during the evolution of galaxies. By studying their role in 2D and 3D scaling relations,  we analyze the connection between effective yields and different feedback scenarios. In this sense, our study contributes to advancing the understanding of the intricate interplay between feedback processes and galaxy evolution.
