Understanding Trophic Cascades
25:21 - 35:08 (09:47)
Trophic cascades occur when species at the top of the food pyramid have a significant impact on the next layer, causing a cascade of consequences throughout the entire food chain. In order for ecological effects to be manifest, the predator must be common enough for a long enough period of time to matter.

Trophic cascades occur when top predators in a food pyramid have a significant impact on the lower levels and cause changes to cascade throughout the system.

Summary
Trophic cascades occur when top predators in a food pyramid have a significant impact on the lower levels and cause changes to cascade throughout the system. Reintroducing predators, such as gray wolves, can change the feeding and browsing patterns of herbivores such as elk, leading to cascading effects throughout the ecosystem.
