Predator Prey Lab Report Essay - 2246 Words

PREDATOR-PREY RELATIONS LAB Background Research: Predators and prey are organisms that interrelate, and they can influence on another’s success in reproduction. Predators are organisms that consume other organisms-their prey. These two organisms evolve together. They live in an environment where they must develop certain adaptations to survive. When an adaptation is developed, it gives an organism certain physical characteristics that create an advantage for survival and can come to dominate in a population. An adaptation aids survival by either decreasing a preys chance of being eaten, or by increasing a predators chance of obtaining food to survive and reproduce. Predators must fight for food. They face density-independent†¦show more content†¦The predators may, however, dash in and pick up any prey being pursued by another predator. Do not hesitate to intrude, any hungry natural predator would not. Hunting time will be 5 minutes. When the teacher or the â€Å"wildfire† comes around and touches any of the students, they must step out of the playing area for fifteen seconds. When told to stop, each student will tally up his â€Å"kills†. If a predator is in the process of capturing a prey when told to stop, he must drop it. 6. Repeat this process for each generation and make the proper adjustments required for each. 7. At the end of the lab, share your data with the class and add up the number of prey killed. Observations: In certain parts of the field, the grass was very tall and the prey that were in that area were very difficult to find. Because of this many predators ignored the grassy areas which caused a lot of competition for prey in the other areas of the field. Certain prey such as the corn was easily concealed in the grass because of its small size. However, in the dirt area, the color of the corn really made it stand out. In the dirt area of the field, the pinto beans were concealed because its camouflage characteristics allowed it blended in with the dirt, but it stuck out in the grass. The black beans were small black so it was concealed it both the grass and the dirt.

The prey involved within this experiment utilized mimisry as their defense stategy. Batesia mimicry, Mullerian mimicry, and aggressive mimicry are all various forms of mimicry. Batesian mimicry is a resemblance of an unpalatable species (model) by an edible species (mimic) to decieve predators. Mullerian minicry is a mutual resemblance of two or more conspicuousyly marked upalatable species to enhance predator avoidanceRead MoreLa Brea Tar Pits2573 Words   |  11 Pagesthese) and one solitary human, a female named the La Brea Woman. The Saber-Tooth Tiger Perhaps the most iconic of these finds is that of the Smilodon, or the North American saber tooth tiger. The great predator likely ended up in the pit due to following prey into the sticky tar — the La Brea lab now holds 166,000 pieces of more than 2200 separate cats.
