Explain how the ecosystem was affected by the missing species for each round of the demonstration. a. Round 1 = without bees, trees and plants could not be pollinated; humans would no longer have honey or enjoy the fruit the sweet taste of fruit due to lack of pollination. b. Round 2 = without humans, perhaps there would be a reverse effect. The ecosystem would perhaps be in better shape if humans were not in the equation since they are the ones who have the biggest impact. c. Round 3 = without flowers, bees would go without part of their food source d. Round 4 = without lichens, plants and trees would suffer because there would not be the necessary nutrients present in the soil around them. 2. Provide one action we as humans engage in that leads to the extinction of each of these components. Action affecting Lichens = Lichens depends on air and water for nutrients which is affected by things such as air travel and exhaust fumes. Action affecting Trees = People cutting down trees is one main way that leads to extinction.

...Exam Review: Lab Essays At least one essay (FRQ) on the exam will be based on an AP laboratory. To prepare for this question, review the objectives for all twelve laboratory exercises. The College Board does not necessarily expect that you have completed that lab, but rather that you have investigated the objectives of the lab. You may be asked to “design an experiment to determine….” You don’t necessarily need to create a new lab; if you have done an activity that would answer the question, simply describe it. For a good response, you should include the following. 1. State a hypothesis [as an “if…..(conditions), then….(results)” statement] Be sure your hypothesis is testable. 2. Identify the variable factor. 3. Identify the control. Be certain to explain the control for the experiment. 4. Hold all other variables constant. 5. Manipulate the variable. 6. State how you would measure the results. 7. Discuss the expected results. Relate the results to your hypothesis. 8. Include steps to replicate or verify. You may be asked to graph data. Be sure to use a graph that is appropriate for you data. Bar graphs are used when data points are discrete (not related to one another), while line graphs are used with the data are continuous. If there is a data point at zero, be certain to extend your line to 0, but do not extend the line to 0 if there is no data point at zero. Other points to keep in mind: 1. Label a...

...Diversity A diverse ecosystem is a stable ecosystem. Without it an ecosystem would have a much harder time recovering from disturbances and resisting perturbations. To measure diversity it is as simple as using a formula called the Simpsons Diversity Index. In the lab we surveyed two separate plots to calculate their diversity. In the species diversity lab we started off by taking a field trip from south campus to Wafer Creek Ranch. The purpose of the field trip was to split into two separate groups and measure the diversity on them. The two plots were marked off with biodegradable flagging and everything in the flagging was examined and recorded. To do the second plot we underwent the same instructions as on the first plot, but the plots were three chains apart. The information gathered on the field trip was then plugged into the formula and the diversity of the two plots was calculated. The results are in the following tables. Site 1 | | Total Trees | Diversity | Location | Sweetgum | 18 | 0.052 | Midstory | Honeysuckle | 1 | 0 | Understory | Water Oak | 1 | 0 | Understory | Smilax | 40 | 0.297 | Midstory | Red Oak | 4 | 0.002 | Understory | White Oak | 8 | 0.011 | Understory | Carolina Buckthorn | 1 | 0 | Understory | | Diversity= 1-.368 | | Site 2 | | Total Trees | Diversity | Location | Black Gum | 1 | 0 | Midstory | Black Cherry | 6 | 0.046 | Midstory | White Oak | 7 | 0.065 | Midstory | Mockernut HIckory | 1 | 0 | Midstory | ...

...Lab Activity Question How Do Abiotic Factors Affect Distribution of Organisms? Answer Along with food and shelter, every organism needs some specific environmental conditions to survive. These conditions, if non-biological, are called abiotic. For survival and existence and growth of every organism, certain environmental conditions are necessary. For example, sun, wind, humidity, water, salts concentration etc. Without these specific required conditions animals would not be able to survive. If disturbance in survival of one single species of organisms will affect the others as well and as a result all ecosystem could get affected. If we talk about distribution of organisms the each and every organisms need some condition in its surrounding, to survive. If, by any chance, any one condition out of the required ones, is disturbed, animal will be disturbed. That animal will definitely prefer to migrate to some other place with better survival and with better environmental conditions. Air pollution can cause decrease in flowering of plants or it can affect health of organisms. Temperature if less can freeze things and if, it is more than required, can melt things. Change in temperature can affect photosynthesis, resulting in affecting both plants and animals. Depletion of ozone layer is one of the biggest threats to our ecosystem, or to all organisms currently. It is depleting day by day and temperature of Earth is increasing due to it. Some animals can regulate their body...

...to dose concentration. Malathion exposure occurs through ingestion, inhalation, and absorption. Human exposure usually results in nausea, headache, and tightness in the chest. Although Malathion is classified as a slightly toxic, lethal doses have been recorded for humans. The lowest lethal dose of Malathion recorded is three times higher for men than women (Pmep.cce.cornell.edu 2012). Alergic reaction to Malathion causes severe dizziness and trouble breathing. Lab tests indicate that rats do not normally have adverse reproductive and development effects from Malathion exposure at low doses and prolonged exposure. High doses can cause teratogenic effects when fed to rats through a stomach tube. Malathion can, however, pass through the placenta of pregnant goats and cause birth defects and increased newborn mortality rates. Chronic toxicity may cause mutagenic risks to humans. Lab test results showed that white blood cells and lymph cells from human cell cultures mutate when exposed to high levels of Malathion. Lab rats fed Malathion showed signs of negative effects on the adrenal glands and the liver, though these were not cancerous effects. According to these studies, there is not enough evidence to suggest that Malathion causes cancer in mammals. Other research from the...
