Or how large can each population grow?"In this activity, students model trophic cascades using cards of organisms from seven different habitats.

The Green World Hypothesis is now widely known as trophic cascade.The concept was championed by three ecologists Nelson Hairston, Frederick Smith and Lawrence Slobodkin (HSS hypothesis) in 1960. They suggested that predators keep herbivore populations in check by consuming them.Disappearance of a keystone species often results in a complete rearrangement of the food web. This is referred to by the term trophic cascade. If the keystone species is at the top of the food chain, the disappearance of this top predator can cause a top-down trophic cascade. If the keystone species is at the base of the food chain, the ...This handout accompanies an engaging and dynamic documentary about the interconnection between keystone species, trophic levels, and ecosystems.
