Predator-Prey Population Research

Decent Essays
We are given the question which factors affect the stability of a Predator-Prey Population. Our goal is to find what factors could change a species population. A stable ecosystem means that a plant or animal does not overpopulate or underpopulate.. If the ecosystem is unstable, then a specie will grow largely, and another one would grow small. Our group collected how the population changed overtime and see if one specie goes extinct in our experiment. We put the experiment on a specific time and also observed what changes if we change things differently, like the grass is off or on, and see if it’s a factor to the stability of a population. We made four trials and in each trials we compared it to one another and see how they are different

    My group is experimenting on a Daphnia. The purpose of our experiment is to test the Daphnia’s with different liquids and see how heart rate increases,decreases or even kill the Daphnia. The variable in our experiment is changing the water content and seeing what the heart rate. The experiment on the Daphnia matters because if we were to have types of elements in lakes that can possibly kill the Daphnia’s, there can be a possibility there species could end. What the Daphnia prefers is open fresh water in their habitat.…

    Ten differing phenotypes of Dottus variegatus will be placed randomly in a colorful board to simulate a population in its environment. The total population includes 100 organisms with 10 representing members of each phenotype. The predator will decimate 25% of the population. Based on which colors experienced high or low levels of predation, the hypothesis that brighter colors will be selected against is tested. The ‘predator’ looks away while another person randomly scatters the 100 dots.…

    I believe that changes to living and non -living parts of an ecosystem impact population within the habitat because if you take away or put something into an ecosystem you are affecting everything around you. Especially if you put in or take out a keystone species. Keystone species are animals that other animals rely on and need to grow. So if you take away an animal that everyone relys on you are hurting all the other animals.…

    Population Growth Lab Populations of different species interact with their environment in a myriad of ways. This may also impact the population, especially concerning its size. The question trying to be answered was how changes in the amount and nature of the plant life available in an ecosystem does, in fact, influence herbivore population growth over time. Answering this question will determine which environmental factor has the greatest impact on the population growth of herbivores. In this lab the herbivores, are rabbits, and the plant life is grass and weeds.…

    The acquisition of resources in animals is an important influence on the structure and actions of a species since individuals want to pass their genes onward to survive. However, interspecific competition affects the availability of these resources and therefore influences the methods by which a species obtains them. Surf Scoter ducks demonstrate a synchronous dive and surfacing pattern, as investigated by LE Schenkeveld and RC Ydenberg, as a tactic to overpower kleptoparasites – animals who rob food from animals of other species – like gulls. In order to determine the mechanism responsible for this collective movement, the scientists investigated the hypothesis that the flocks will dive more synchronously, and therefore surface at the same…

    Explain how human activities can cause an imbalance in biogeochemical cycling and lead to problems such as cultural eutrophication and fish kills. Biogeochemical cycling is defined as the chemical element flow between the living and nonliving components of the ecosystem. This is the cycle of nitrogen, phosphorus and carbon being converted into organic substances of plants and animals that are released back into the environment. There are three ways that human activities cause an imbalance of biogeochemical cycling on a daily basis.…

    The Cane Toad

    • 499 Words
    • 2 Pages

    The cane toad, like the hemlock wooly adelgid was able to thrive in its introduced environment due to similar abiotic condtions as those in its native habitat as well as a lack of natural predators (which were in its native habitat). Because neither have natural predators that are able to keep them under control, both were able to wreak massive effects on the ecosystem. Both caused major impacts on the ecosystem by damaging the populations of one species (or group of species) with rippling repercussions; however, while how these effects occurred differs mainly due to the differences in the species directly affected. Because the hemlock wooly adgelid damages hemlock tree populations, it effects the population in a bottom up manner; meanwhile, because the cane toad mainly has caused damage to top predator populations, it effects the population in a top down manner. Neither invasive species only affects the animals that they directly harm.…

    Conclusion The hypothesis stating if certain stimuli (light, darkness, bran flakes, and apple slices) are placed in a chamber near a group of ten mealworms, then during 3 minutes a portion of the mealworms will have moved towards the stimuli, was refuted by the data showing how zero mealworms migrated into the stimulus chamber, during any point in any of the trials using each of the stimuli and the one trial without using a stimulus. Discussion The student designed experiment to investigate a mealworm’s response to a variable had the same results for each trial.…
