Owl Pellet Lab

Michael Canfield 10/15/09 APES Owl Pellets-A Study of Food Webs The material object of this laboratory is to notice the type of species tack in an beak guess and how many of that particular species is present. It is also to observe the food web of an schnozzle by examining its pellets. Once we effect off information about our specimen, we compared it to the data our whole segmentation obtained. In total, the class examined 25 contrary pellets, and establish 55 puppets within the pellets. This means that there were 2.2 animals per pellet. The information from the class told us that owls spend a penny a varied eat regiment. There were 11 disaccordent species found within the 25 antithetic pellets. The numbers varied however.

The average was again, 2.2 animals per pellet. This lab could also help control what kind of animal the owl prefers or has the least trouble target areaing. As tell before, Townsend moles were found most out of the 11 species discovered in the lab.

cosmos the most, atomic number 53 may be able to determine that owls prey on them the most out of the others, and the owl preys the least on the Coast moles and Creeping moles (because they were preyed on the least fit in to the information). This information could however be misleading at the equal time. Despite the facts bein! g presented in the lab, it’s only a small experiment. If a larger scaled experiment was held, results could differ tremendously. The environment may hold a great dole out of different information. For example, there may be an overabundance of one species, making them more accessible, which would then in a resultant time, heavily reduce their species. This could flip the results of an...If you want to get a full essay, order it on our website: OrderEssay.net
