Willie Beyond Scared Straight Full Name, On a quiet spring morning, a resounding "Slap!" reverberates through the air above a remote stream leading to Lake Yellowstone. } else { Energy transfers in a food web. You do not need to examine the source code at this stage. Introduction. Introduction: The Lotka-Volterra model is composed of a pair of differential equations that describe predator-prey (or herbivore-plant, or parasitoid-host) dynamics in their simplest case (one predator population, one prey population). " /> In an effort to help preserve the species, scientists caught 20 of the remaining seals and used them to start a new population in the northwest Pacific Ocean. } One very important phenomenon of trophic ecology is known as a trophic cascade, which describes the indirect control that a top predator exerts on species at lower, nonadjacent trophic levels.
