Natural Selection for the Birds Lab Report Essay

PurposeTo determine which dames with which beaks live best in their environment depending on the type of food avai laboratoryle.QuestionWhat is the effect of the type of food available on the frequency of diametrical types of bird beaks?HypothesisIf the food type changes in the environment, then the amount of each type of bird beaks will change because birds with beaks more suited to the available food will be more undefeated over time.VariablesThe independent variable of the lab is the type of food that is available to the birds. The dependent variable of the lab is the frequency of each type-size and shape-of beaks.Materials100 sunflower seeds100 raisins100 grains of rice2 forks2 spoons2 knivesPlastic formProcedure1. Gather around the edge of the table stuff, mixing the three groups plum evenly. 2. Pick up food pieces only with your tool, using the pair of utensils in one hand, simulating the action of a beak. 3.

When fruit was taken away thither was a decrease in the number of birds tha t flock X contained. Flock Y consumes mostly seeds. in that respect was no effect on flock Y when fruit was removed. Due to the fact that flock Z eats mostly insects, the flock was not affected by the removal of fruit.ConclusionIn this lab I learned about how favorable traits atomic number 18 important when nature selects what organism will survive and pass down its genes for the next generation to inherit, I also learned that most species learn to fit to their environments so that they can have a favorable trait to be able to survive in their environment. I was able to observe that in the wilderness you need that favorable trait so that you are able to reproduce and pass down your genotypes for the next generation of you species to inherit. Igained useful skills such as how to determine the next generations population by analyzing results from experiments I conducted relating to the bird populations
