O Prey will then begin to increase and the cycle starts over This lesson is designed to help teach students how the predator-prey relationship affects our ecosystem through interactive games and scavenger hunts as well as discussion and application of knowledge through a mini project. O Predator numbers will decrease as prey numbers decrease Children can check their work using the accompanying. Blank boxes are also included for children to come up with their own organisms and descriptions to challenge their partners. O Prey numbers will decrease as predator numbers increase This cut and stick activity gets children to match the given predators with their prey, and identify the correct description of how the predator catches its prey. When lemming populations become too large, they consume all of the moss that is their food. Lemming populations go through cycles of growth and decline. O As prey population increases, this is followed by the predator population increasing. A well-studied predator-prey relationship is that of the snowy owl and the lemmings, a type of rodent, that are their prey. ![]() When population numbers of the predator and prey are graphed over time the graph show: The Predator/Prey model reveals that the population size of the predator oscillates with the population size of the prey creating. The Predator/Prey model aka Lotka-Volterra model is based on an equation that describes interactions between two (predator and a prey) species in an ecosystem. ![]() Species A will benefit by feeding on species B. Antipredator defenses, however, also carry fitness costs. Predators (species A) are animals that prey (hunt, kills, eats) other animals (species B). Predation exerts an ultimate selective pressure on animal behavior: the fitness consequences of an ineffective behavioral response are immediate and irrevocable. This game and graphing activity is a fun way to represent the predator prey model showing how each population responds to the other.Īfter completing this activity, students will be able to understand: They are bigger than their prey and more agile.Summary: In this lesson, students play a simulated board game of Clerid Beetle vs Mountain Pine Beetle. These animals are of a sturdy constituency, coupled with a strong set of jaws and sharp dental constitution to help them tear their prey apart. These activities build on the Predator vs. Comparison Table Parameters of Comparison Predator Prey Meaning The section of animals that are built to prey on other animals The section of animals that are built to be preyed upon by other animals Dental Constitution They have a sharp and sturdy dental constitution to help them tear their prey apart They have a dental constitution that is more suited to chewing grass or anything that is not difficult to be torn apart Size They aren’t always bigger than the animals they prey upon but are more powerful Sometimes these animals are bigger than their hunters but weaker Food Chain Stages They constitute the last or stage nearing the end of the chain They come before the predators Dependency They are solely or largely dependent on their prey for survival They aren’t dependent on the predators at all What is Predator?Ī predator can be defined as a section of animals that is built to prey on other animals. These animals are of a sturdy yet weaker constituency, coupled with a dental constitution that is more suited to chewing grass or anything that is not difficult to be torn apart.
