Lab 3 – Biodiversity Demonstration 1: Interdependence of Species Table 1: Interdependence of Species Results Round Species Missing (Bead Color and Name) 1 White bead represents lichen 2 Blue bead represents humans 3 Red bead represents flowers 4 Orange bead represents trees POST LAB QUESTIONS 1. Explain how the ecosystem was affected by the missing species for each round of the demonstration. a. Round 1 = Lichen is missing in this round. They are very important for creating soils from which plants can obtain nutrients. Just like all living, Lichen also need nutrients and energy to grow. Nutrients can be obtained from air, water, and from substrate organisms. Energy can be obtained through the process of photosynthesis. b. Round 2 = blue bead which represents humans is missing. Humans depend on bees for honey and also fruits that are pollinated by the bees. c. Round 3 = Missing of red beads indicates absence of flowers. These flowers depend on trees for shade and wind protection and soil for nutrition. d. Round 4 = in this round orange bead representing trees are missing. Trees depend on soil for food (nutrients). Fruit producing trees, in turn depend on bees as a means of pollination. 2. Provide one action we as humans engage in that leads to the extinction of each of these components. Action affecting Lichens = indiscriminate use of land Action affecting Trees = cutting and deforesting Action affecting Flowers = cutting of trees indirectly affect the growth of flowers Action affecting Bees = absence o flowers would affect the lives of bees 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 = protect trees Action 2 = avoid or minimize use of automobile so that pollution can be curtailed Action 3 = plant more trees Experiment 1: Diversity of Plants Table 2: Number of Each Plant Species Present in Pot 1 and Pot 2 Species Observed Number in Pot 1(sunlight) Number in Pot 2(shade) Zinnia 3 2 Marigold 4 2 Morning Glory 6 3 Cosmos 5 2 Ryegrass 4 3 Total Number of Species in Pot: 17 12 POST LAB QUESTIONS 1. Develop a hypothesis on which pot you believe will contain the highest biodiversity. Hypothesis = Pot no 1 will contain the highest biodiversity 2. 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 = Accept. The results indicate clearly that the pot which is in sunlight has higher rate of survival for the plants, thereby increasing the chances of biodiversity. 3. If each pot was a sample you found in a group of wildflowers, would you determine based on the diversity of flowers that the ecosystem is healthy? Why or why not. Answer = Yes the observation would indicate the healthiness (or the absence of it). The reason for this is that plants grow in sunlight and they get all the nutrients. So if there is biodiversity, it indirectly indicates that the ecosystem is healthy. 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 means variety of life on earth. Number of species of plants, animals, microorganism, various genes prevalent in these species, different ecosystem existing on the planet, are all part of a biologically diverse earth. An attempt should be made to conserve and put in place strategies that help in sustaining the development. This is part of an integral approach and will help in preserving the biodiversity. Almost all living creatures are borne out of biological diversity in some form or the other. For example a large no of plat species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms. Healthy ecosystems can better withstand and recover from a variety of disasters.Another example is deforestation threatens many species such as the giant leaf frog References Any sources utilized should be listed here.
