Predator-Prey Lab Report

Predators affect the size in population . The population can either decrease or increase. If the population number increases then that means that the number of preys are high. The point of this lab is to figure out the factors of the stability and the unstability. The size of a predator population and prey population goes in a cycle over time. When the population of the predator-prey results in both Predator and Prey still living over time is known as stable. A predator-prey that has died as one or more species is known as unstable. A stable graph would be shown with species decreasing and increasing. A unstable graph would show no species or it will start out with species while the species dies off. The stable graphs will look like this because when the population is stable it goes on. Which factors affect …show more content…
Try to make it unstable , because when the stability of the predator-prey population size relation is affected that means the species are extinct. When it's extinct it makes it unstable. Wonder when factors affect the stability of a predator-prey population size relationship?
Well a way to figure this question out is to do an experiment. There are thirty procedures to begin the experiment. First thing the scientist did was went to Google Classrooms. Second, the scientist clicked the August 30 assignments. Third,the scientist scrolled down to the web www.netlogweb.org , then clicked on the library drop down , chosed the “Sample Model Biology/ Wolf sheep Prediction¨. Fifth, the scientist scrolled down where there was a toolbar that said “setup”. Sixth, the scientist went down to the Grass settings, checked the box that said “ Grass”. Seventh, the scientist changed the grass growth to thirty-six. Eighth,the scientist went down to sheep settings and changed the number of initial-number-sheeps to seventy-two. Ninth, the scientist scrolled down to sheep gain-from-food and change the number to
