Top-down trophic cascade models predict that ecological systems with even numbers of trophic levels will have low plant biomass and that systems with odd numbers will have high plant biomass (1-3).Top-down effects may also alter species diversity (4, 5).Although tests in aquatic systems often support these models (), the occurrence of top-down trophic cascades in terrestrial systems is ...Directions: Answer the following questions while watching the video Some Animals Are More Equal than Others: Keystone Species and Trophic Cascades. 1. What is the difference between producers and consumers? Consumers eat producers and producers generate their own food and food for others. 2.The positive, top-down indirect effect of wolves on beavers goes through many trophic levels. Beavers are "engineer species",which create habitat for many others; by promoting certain plants, they have a positive"bottom-up" effect on the ecosystem. So, the thistrophic cascade, triggered by the restoration of wolves, flows both ways.New & Notable.

Then compute the force on the hinge and on the support. Verified answer.Complex food webs support diverse ecosystems.

However, changes in one part of the food web may cause a trophic cascade that affects organisms across multiple trophic levels. For instance, removing a top predator may cause its prey to become ...182 Users Description This interactive module explores examples of how changes in one species can affect species at other trophic levels and ultimately the entire ecosystem.
