ewtn live adoration Trophic cascades are powerful interactions that strongly regulate biodiversity and ecosystem function. Trophic cascades were originally thought to be rare, but now we understand that they occur across diverse terrestrial, freshwater and marine ecosystems, and are common features of many green plant communities, including vascular plant assemblages, long thought to be resistant to consumer control.Remove the sea otters and the kelp forests disappear. Paine called these cascading effects of one species downward upon others "trophic cascades." [PAINE:] A trophic cascade is when you have an apex predator controlling the distribution of resources, and they lead to these cascades of indirect effects.
