Mutually beneficial interactins, in cntrast, may becme s interdependent that each rganism requires the ther fr survival. Althugh the species invlved in these cmpetitive, predatry, and mutually beneficial interactins vary acrss ecsystems, the patterns f interactins f rganisms with their envirnments, bth living and nnliving, are shared.

Transfers f matter int and ut f the physical envirnment ccur at every level. Decmpsers recycle nutrients frm dead plant r animal matter back t the sil in terrestrial envirnments r t the water in aquatic envirnments.
