Meta-analyses of trophic cascades find mixed support for the hypothesis that prey species richness dampens cascade strength, and suggest that factors such as ecosystem type and predator metabolism are more important (Schmitz et al. 2000; Borer et al. 2005).

“Every man’s life ends the same way. It is only the details of how he lived and how he died that distinguish one man from another.” These words from literary giant, Ernest Hemingway, illuminate his dedication to a life well lived.Trophic cascades applied. Trophic cascades are of interest beyond the insight they give us into the function of aquatic ecosystems. They have been directly applied to problems associated witheutrophication in lakes, where excessive nutrient input such as from fertilizers leads to blooms of undesirable phytoplankton (Kitchell 1992; Carpenter & Kitchell 1993).Exploring trophic cascades answer key Trophic cataracts refer until impacts that reach beyond adjacent trophic levels.

A trophic cascade affected the entire food web in Yellowstone, causing some organisms to experience decreases, and others to grow rapidly. Biodiversity increased when the wolves disappeared and more species were able to flourish without the wolves. A trophic cascade irreversibly ruined the ecosystem in Yellowstone--destroying biodiversity forever.
