Predator Maniacs Background Being able to explain what is meant by natural selection -Natural Selection is where organisms adapt to their environment and tend to survive and produce more offspring. The theory of Its action was founded by Charles Darwin and is now believed to be the main process that brings about evolution. Being able to explain why changing environments change population characteristics. -It is because each environment has a different type of species living in it and might not be capable of catching the prey because of Its Miming habitats.
Being able to explain what Is meant by the pressures of predator populations “mold” prey populations. ;There are so many predators in the wilderness and a lot of predators are having competition with other predators in order to survive. Being able to explain how the prey population also “mold” the predator populations. -The prey population “molded” the predator population because of how much prey It is for the predator and how little there is to the population for the predators.
Being able to explain why this would be a continuous process. -This would be a continuous process because in the animal mignon in order to survive you have to fight for your food In order to live, and is probably why the predator’s rate Is dropping. Being able to explain why variation within a species is the “raw material” of natural selection. -Variation within species is the “raw material” because of how deferent each species is and depending on what kind of food they need to eat in order to live the right amount of time.
Problem Which predator is the best adapted to catching the prey? Hypothesis If the predator has the most logistic abilities In capturing the prey, then that predator as a higher chance of getting that prey, because it’s something that animals has is who has the best abilities of its own into capturing the prey with. Materials -Black Beans -Pinto Beans -Forks -Small plastic Knives -Small White Beans -Plastic Spoons ;Popcorn Kernels -A grass field -Broken Forks -Styrofoam Cups (6-8 oz. Ups) -Stop watch Procedures 1) Distribute 100 of each kind of predator in the grass. Know exactly how many beans 1 OFF 3) Give each member of one group forks, of another group spoons, of another group knives and the last group broken forks. ) Every student would get a Styrofoam cup. 5) Instruct the students that they are each individual predators with structural variations. The beans are the prey. The prey must be picked up with the feeding mechanism (forks, knives, spoons, or broken forks) and placed in the model mouth (cup).
No scraping or pushing of the prey into the mouth is allowed – the cup may not touch the hunting ground area. They may, however, dash in and pick up any prey being pursued by another predator. Don’t hesitate to intrude, any hungry natural predator would not. Hunting time will be 5 minutes. When told to stop, each student will tally up his “kills”. If a predator is in the process of capturing a prey when told to stop, he/she must drop it. Observations The beans could not be seen in the taller grass area for the predator to quickly see on.
Capturing the beans were small and were easy to misplace them. Hearing everyone panic when they didn’t make enough to survive. The beans were blended into the environment to get rid of their scent. Although they are beans they may not taste very well. Data Analysis Each column represent the predators, and the numbers represent how much prey the predators had caught in each generation of their species. This graph tells us the white prey were caught exceedingly well most of the times in the generation.
It also tells us that during the first generation of all 4 predators most of the amount that had shown were more equal to the numbers of preys than the other generations of how many preys were caught because of the amount that the predators had caught from the prey. Conclusions This lab was done to show us how each of the predator has to use of their own in until each of the predator is satisfied with the amount they had had. Each predator needs to use their own body parts to capture the prey (like the broken forks) we have to use our parts to make the best out of it in order to survive.
This lab was shown how predators capture their preys by having competitions with each other and to see who gets to survive longer than the other species itself in order to live. The prey best adapted to the environment is probably the popcorn kernels because of how it blends in with the grass. It is best adapted because that prey is best fitting for that yep of environment for it to live at and not to be caught by many predators. The spoon captured the white bean the most because of how fast it could catch the prey and how easily visible that prey is seen by all the other predators as well.
The control group was the prey (beans) and the experimental group was the predator (utensils), the independent variable would be the predator and the dependent variable would be the grass field because it needs the preys cooperation in order for the preys to live as well. For the control variables it would be the predators because of how much ere the need in order to survive from one generation to the next of the species and is the main thing in the time frame.
