Predator and Prey Report

HYPOTHEIS:
H0: I predict that there will be no difference between animals that have strong genes and weak genes.
HA: I predict that animals with strong genes would have more opportunity to survive than the ones that have weak genes.

INTRODUCTION:
Natural Selection is the process by which populations are able to adapt and evolve. In simple words is just the rate of reproduction and mortality. Those organisms who successfully adapt to the environment survive and reproduce organisms able to adapt and survive too. The purpose of this activity is to see how natural selection happen and see which animals evolve and adapt to their environment in order to survive. Animal struggle for existence, …show more content…

The students were divided into three groups and each group represented three species of birds (the predators) with different beaks. Spoons, knives and forks represented the types of beaks, they also used glasses, and the glasses represented their stomach. White, black, red and green beans represented the prey. The beans (preys) were randomly spread on a marked area on the grass. The teacher had a clock set to 1 minute during that minute everyone begun hunting, the glass was no allowed to touch the ground, after one minute everyone counted how many beans(prey) the got and recorded the results on the data sheet. Then everyone formed a line from lowest to highest, in numerical order for example from 21,20,19,18,17 and so on, the first ten with the lowest amount of prey(beans) died and the next ten with the highest amount survive if there was one in the middle of the first ten and the second ten (neutral) survived but with weak genes. Then the ten that survive randomly selected new beaks (spoons, knives, forks) and gave them to the ones that died, depending on which type of beak (spoons, knives, forks) you got you joined a new group or stayed with the same one. Then the process of hunting started again doing the same thing two more times (generations1, 2, and

Skittlefish Lab Report

598 Words | 3 Pages

Natural Selection is the concept that organisms better adapted to their environment tend to survive and produce more offspring. This leads to the creation of populations and diversity of life within them. In the Skittlefish Lab, many separate occurrences can be observed which detail and explain how Natural Selection works on a population over a period of time. Certain adaptations in a species in its entirety may display how individuals impact the whole population as they pass their traits onto their offspring, which do the same. This lab required students to observe the individual “Skittlefish” and “Sea M&Ms” in different environments as they camouflaged and hid from predators.

A longer span of hunting time–5 minutes compared to 3 minutes–would have been helpful towards the experiment due to the amount of beans that were spread in the grass. If a longer hunting time was provided, the accuracy of the experiment would also increase. More people in each predatory capturing group would have been helpful. The experiment would give more accurate numbers if more people were added to the groups. It would also be beneficial if the beans were more evenly spread across the grass to avoid major clumps.

Natural Selection Lab Report

I conducted a lab that would investigate the question of whether or not camouflage favored natural selection. If an animal blended into its surroundings, I wanted to know if it could more effectively evade predators and survive as a species. I hypothesized that if I were a predatory bird hunting for mice in a field, then the mice that were camouflaged with their environment would be harder to find. The results did not support my hypothesis, as most of the mice (often more than 2/3) that had a similar appearance to the field they lived in were hunted, and did not escape predators. You can determine if a predatory bird would have more difficulty finding mice that were camouflaged with their environment.

Predator-Prey Lab Report

1347 Words | 6 Pages

Organisms can evolve to enhance their ability to catch prey, or flee predators. Coevolution occurs in a predator-prey relationship when the prey evolves in response to pressures exerted by its predator. The predator then evolves in response to the changes in the prey (or vice versa). Inheritable adaptive traits evolve through natural selection, the process by which organisms that have developed favorable traits are capable of surviving and reproducing at greater rates, thus passing their adaptive traits to their offspring. Birds and caterpillars have a predator-prey

Four Theoretical Predator-Prey Relationships

365 Words | 2 Pages

As perceived in the graphs above there are indeed four different theoretical predator-prey relationships, where they could be differentiated by the difference in conditions of the predator and prey populations. In addition, one assumption that applies to the hypothetical predator-prey system is that the reproductive rate of the predators depends on the number of prey and predators available. Another significant assumption that could be taken into account is that the mortality of the prey specie depends on the population sizes of both the predator and prey species (functional response). According to the data used in lab, the stable oscillations (Figure 1) was crafted by imputing a median value of 0.04488 as the per capita predator mortality

Natural Selection And Change The World: Chapter Analysis

This chapter was about how natural selection can be change the world. Darwin decides to open with, “But the mere existence of individual variability and of some few well-marked varieties, though necessary as the foundation for the work, helps us but little in understanding how species arise in nature,” (60,Darwin). Darwin has shown that each living species has a job or can help make this world a better place. Darwin has had ideas on how each species originated on earth. We are know that animals and humans are able to reproduce more of itself, which allows its traits to be passed on.

Dottus Predation Lab Report

The starting population of the experiment contained 100 organisms that had 10 different Dottus Variengatus phenotypes. A multicolored-city board was used to simulate the environment where these organisms lived. To perform the experiment, groups of three were formed. The first member had to act as a new predator of the population, the second member was assigned to randomly disperse the colored dots on the board, help keep count of the consumed dots, and collect materials at the end of the experiment. The third member had to collect the prey from the predator, and help keep count until 25 dots were collected.

The Influence Of Natural Selection

930 Words | 4 Pages

As geology strongly proclaims that each piece of land has undergone and will continue to undergo great physical changes, we may expect to see changes amongst organisms that would be varied under the influence of nature, in the same manner as they generally would have under the changed conditions of domestication. Second to that if there were to be any variability in nature it would be a product of the unaccountable fact of natural selection or survival of the fittest. It has often been stated that the amount of change within nature is strictly, meaning that organisms and plants can only undergo a certain amount of change at any one time. Modern day man is able to act on external characters and can produce a great result within a short period

The Pros And Cons Of Natural Selection

918 Words | 4 Pages

Depending on the conditions of the environment, the organisms may pass down selected traits to their offspring. These selected traits will allow for the next generation to better adapt and survive longer ["Natural Selection and Speciation - Biology."]. One example of evolution through the process of natural selection is that of the Viceroy butterfly. The Viceroy butterflies were facing extinction a little more than 100 years ago due to their inability to protect themselves or hide from their predators; mainly birds.

What Is An Example Of Natural Selection

if there are mutations to live at high altitudes, it will increase quantity in survival of infants, if those who have a mutation pass it on to their offspring, in a certain way, all the good mutations in a single individual, producing a living being with great success, and relegate all bad mutations to another, which will not get offspring, so that bad mutations will disappear from the population. Natural selection is only the process of adaptation within a species and many examples of this can be observed. Natural selection allows mutations to pass to the offspring, the conditions of an environment favor or hinder, that is, they select the reproduction of living organisms according to their peculiarities and as a consequence, mutations allow
