Nutrients may be obtained from the air (including dust), water, and from the substrate organisms grows on” (Botcher & Rexes, 2012). They obtain energy through photosynthesis, which is the role of the algal partner. They may also be incidentally fertilized by bird and insect dung. B. Round 2 = Forest flowers and plants depend on trees for shade and wind protection as well as soils for nutrients (Botcher & Rexes, 2012). C. Round 3 = “Bees depend on flowering plants and trees for food” (Botcher & Rexes, 2012). . Round 4 = Humans are influenced by bees for honey and fruit from trees they fertilize (Botcher & Rexes, 2012). 2. Provide one action we, as humans, engage in that leads to the extinction of ACH of these components: Action affecting Lichens = when farmers use an abundance of insect repellent, chemical plants use dangerous compounds, and the various additional contaminants from everyday households lead to the extinction of lichens. Action affecting Trees = trees are cut every day.

Humans use trees for various reasons such as to build houses, make paper, and any other projects. Trees takes a while to grow, so if humans are cutting them down faster than they grow, then we won’t have many left for oxygen and the many of the other natural things are needed for. Action affecting Flowers = the soil for flowers are not as healthy as it should be. The soil is continuing to become contaminated by humans. Humans don’t plant enough flowers which also help the bees pollinate. Action affecting Bees = the air quality is affecting bees.

Also people are killing bees as they are suspected to harm humans so humans kill them. There aren’t many man made places where bees can go nest to make more 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 = humans can use less pesticides when growing crops and grass. Action 2 = humans can plant more trees and recycle more. Action 3 = humans can help Paulette bees but not to the extinct where they will over populate.

Experiment 1: Diversity of Plants Table 2: Number of Each Plant Species Present in Pot 1 and Pot 2 Species Observed Number in Pot I(sunlight) Number in Pot 2(shade) Zinnia 5 Marigold Morning Glory Cosmos Regards Total Number of Species in Pot: 13 16 1 . Develop a hypothesis on which pot you believe will contain the highest biodiversity. Hypothesis = If the plant that is constantly exposed to sunlight, then the plant will grow faster. 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 = reject my hypothesis since both plants started to grow at the same time. 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 = I would look at the growth of the samples were healthy. By observing he plants for a little over 4 days not many plants grew. At the same time, both samples grew fairly quickly. 4. How does biodiversity contribute to the overall health of an ecosystem?
