Friday, October 26th, Mrs. Barrera's Environmental Science students at Eagle Pass High School learned about Trophic Cascades.
Trophic cascades are powerful indirect interactions that can control entire ecosystems, occurring when predators in a food web suppress the abundance or alter the behavior of their prey, thereby releasing the next lower trophic level from predation.
Students played the roles of producer, rabbit, snake & hawk and observed how density-dependent and density-independent factors affected their populations.
Go Eagles!
