Biodiversity Lab Essay1. apologize how the ecosystem was change by the missing species for distributively round of the demonstration.a. Round 1 = white bead representing lichens. Our science lab reading for the experiment stated that lichens be instrumental in the development and receive aims for all species. The schoolbook stated, Lichens play a part in the creation of soils from which whole kit and boodles can obtain nutrients. Like all financial support organisms, lichens need nutrients and energy to grow. Nutrients may be obtained from the air including dust, water, and from the substrate organisms grows on obtaining energy finished photosynthesis, which is the office of the algal partner. They may overly be incidentally fertilized hybrid and insect dung (Bottcher Rex, 2012, p. 43). With the information obtained from the reading, without lichens, bees, trees, flowers, and military man will all have negative repercussions.b. Round 2 = Yellow bead, representing b ees. No bees and lichens the trees will non be pollenated, which will result in a loss of a viands sourcefor adult male since bees pollenate trees and flowers for food. Without bees to pollenating, the ecosystems takes a nonher dramatic step towards extinction. One study stated, Deduction from floral structure indicates that the flowers of many an(prenominal) crops and wild plants ar adapted for bee pollination.Further experimental studies of pollination are much needed, to see whether brusk pollination limits seed set, and which insect species are potential or actual pollinators. The adequacy of pollination of a given plant species will vary regionally with climate, habitat and the nature and density of the local pollinator confederation (Corbet, Williams, Osborne, 1991, para. 3). Minus the bees, the results for all other species will be negatively impacted.c. Round 3 = Orange bead, representing trees. The trees are dependent on lichens and with lichens removed. The trees w ill non have enriched soil to keep living. This is the reason for loss of oxygen for all species who require it and without bees, the fruit that more(prenominal) or less trees produce will cease to exist, causing food shortages and lack of shade and protection for flowers and humans (Bottcher Rex, 2012).d. Round 4 = Red bead, representing flowers. Lichens removed the soil could not adequately support nutrients required to keep alive. The flowers needs protection and shade from trees to move life and the trees were removed receivable to soil composition and loss of lichens from ecosystem.2. Provide one action we as humans engage in that leads to the extinction of each of these sections.Action affecting Lichens = The use of pesticides, chemicals, other pollutants, and people cause damage to this component that can lead to the irreversible impact on the lichens.Action affecting Trees = The destruction of soil and pollution, a major area where humans are impacting trees is thro ugh the removal of lumbers for trees to support human projects and constructions. Ninety-three per centum of the timbreland in the United States isPrivately owned (Hazel baker, 2008, para. 1).Action affecting Flowers = Even though our chemicals are cleansing these flowers and making the soil contaminated and resistant to flower species. The use of pesticides and other chemicals, flowers are not engineered wish crop seed to survive these chemicals.Action affecting Bees = Due to several human factors, bees are world threatened and destruction of their habitat is the number one reason. For a habitat to remain successful and sustain populations it must provide nesting sites and a seasonal succession of forage, and humans are depleting these areas through population appendage and industrialization (Corbet, Williams, Osborne, 1991).3. Provide three specific actions that humans can take to minimize our impact on the ecosystem and ensure the survival of lichens, trees, flowers, and bees.Action 1 = Bees are a critical part of the ecosystem. Humans need to ensure habitat sustainment to sustain bee populations do not deteriorate to levels that cannot be corrected.Bees need food (nectar, pollen) provided by insect-pollinated plants in order to reproduce and produce more bees (Corbet, Williams, Osborne, 1991, p 2). By creating hives and environments that are conducive to bee sustainment, it is possible that strides can be to reverse the downward trend in populations. This is critical as one study showed. It stated that the loss of bees was a domino effect to other species. It stated, If bee pollinated flowersdo not seed, the integrity of Europes remaining semi native vegetation will be destroy and the colorful flowers of the countryside will be lost. This in turn will deprive many other phytophagous or seed-eating insects, birds and small mammals of their host plants and/or food,with consequent further loss of species diversity(Corbet, Williams, Osborne,1991, p 2). by the saving of the bees, the increase of pollinated of other species helps ensure survival of flowersAction 2 = Humans can obstruct polluting the soil and surface of lands through illegal dumping, spills, and so on that contaminate and kill lichens that are critical in soil creation and providing nutrients to other plants and trees. With the help of government agencies and through stricter enforcement, creation of neutral pesticides and chemicals, and other products to rule in harm to the environment and providing a wellnessier ecosystem for all life to thrive.Action 3 = The best federal agency to save our tree populations is to protect the public lands from forest harvesting and ensure there environmental regulations for moneymaking(prenominal)ised logging businesses.93% of the forestland in the United States is privately owned (Hazelbaker, 2008, para. 1). That means that there are hole of lands available for harvesting and ensuring forests do not die off and leave the negative impacts and loss of a precious resource. Due to the benefits that can be found in the national and state forests, such as clean air, fresh water, etc. I feel it is a good practice to prevent commercial access on these lands. These lands serve as a refuge to wildlife and often provide unique opportunities to the citizens who seldom get an opportunity to experience nature and these environments.POST LAB QUESTIONS1. Develop a hypothesis on which pot you believe will contain the highest biodiversity.Hypothesis = One pot has at once exposure to temperateness it will have the highest level of biodiversity2. Based on the results of your experiment, would you reject or accept the hypothesis that you produced in question 1? Explain how you determined this.Accept/Reject = Reject. Table 2 of this experiment, the pot that was set from all windows had a greater diversity of growth from the random seeds planted in it, versus the one with direct sunlight. The pot that had direct su nlight yielded smaller totals in each of the basketball team plants planted in each pot as well as a smaller overall plant yield. While some individual plants had close results, there was a total difference of the total plants of 48.3. If each pot was a warning you found in a group of wildflowers, would you determine based on the diversity of flowers that the ecosystem is flushed? Why or why not. come = I would say that each sample would yield results of a healthy ecosystem based on the diversity in each sample. Each plant has samples ofall five seeded plants planted and yielded results in two weeks. While both specimens yielded results, I would say the ecosystem sample that was not in direct sunlight did show signs of a healthier ecosystem and believe that the temperature and light changes the other sample was exposed to could have played a part in the results. Example, living in Arizona my mansion house has low humidity and low temperatures at night and moderate temperatures i n the mid-morning through sundown that affected the sample with sunlight exposure.The other sample, the one away from the windows, sat in the middle of my apartment on a shelf in the laundry room, with no direct exposure to sunlight, but not altogether in the dark, had more stable temperatures and had constant ambient light exposure through the day and did not suffer cold drafts from the windows that could have made the other specimens plants yield lower results.4. How does biodiversity contribute to the overall health of an ecosystem? Provide specific examples and utilize at least one scholarly resource to back your answer.Answer = Biodiversity contributes to all levels of an ecosystem.Biodiversity, short for biological diversity, includes the genetic variation between all organisms, species, and populations, and all of their complex communities and ecosystems. It also reflects to the interrelatedness of genes, species, and ecosystems and their interactions with the environment (B ottcher Rex, 2012, p. 39). The experiment with the two pots is similar to that of a forest ecosystem. A functioning forest ecosystem, for example, exhibits rates of plant production, carbon storage, and nutrient cycling that are characteristic of most forests (Chapin, Costanza, Ehrlich, Golley, Hooper, Lawton, Tilman, 1999, para. 9). The five seeds that grew in each pot were sharing nutrients from the soil and the evidence showed that certain species thrived in numbers over the others that grew.As one research analysis on biodiversity, there are always species interactions that have impact on the other species. The study stated, Ecosystem functioning results from interactions among and within different levels of the biota, which ecologists describe as a nested hierarchy. Example, greenplant production on land is the end product of interactions of individual plants nested within populations interactions among populations nested within a private species interactions among a variety of species nested within a group of functionally similar species and so on up to the level of interactions between different types of ecosystems nested within landscapes(Chapin, Costanza, Ehrlich, Golley, Hooper, Lawton, Tilman, 1999, para. 11). While some ecosystems continue to exist, some thrive, the harm world done to, and overall health of the ecosystem is dependent on the actions we as humans take. Our society has destroyed ecosystems, species, etc. and pollution, air quality, and other factors have seen many ecosystems destroyed and pose extinct. From current research, we have identified the interest impacts on ecosystem functioning that often result from loss of biodiversity-Plant production may decline as regional and local diversity declines-Ecosystem resistance to environmental perturbations, such as drought, may be lessened as biodiversity is reduced.-Ecosystem processes such as soil nitrogen levels, water use, plant productivity, and pest and disease cycles may beco me more variable as diversity declines (Chapin, Costanza, Ehrlich, Golley, Hooper, Lawton, Tilman, 1999, para. 11). In the end, if action is not taken soon, the devastation created through our industrialization, over population in countries across the world, etc. can lead to consequences that can see more devastation and harm that may not be able to be undone if our society fails to take the necessary action to sustain life of all ecosystems.ReferencesHilmo, O., Sstad, S.
