Earlier this semester, we learned about the biodiversity of the Los Angeles River and you collected data on trash in your neighborhood to help the Council for Watershed Health better understand the threats that our waterways face from trash. Now, you will be revisiting the same location to collect a second trash assessment. These data are important in helping CWH understand how the quantity and types of trash changes over time - critical information for designing effective trash mitigation programs.Assignment RequirementsStep 1: Complete your trash surveyYour second trash survey must be completed in the same location as your first trash survey. Please locate the same storm drain and gutter and complete your trash survey there. If you are unable to complete your trash survey in the same location, please send me a Canvas message and we'll come up with an alternative plan.Use the ArcGIS123 survey (Links to an external site.) to complete your second trash survey. You can use either a web browser or the ArcGIS Survey123 field app to enter your data. As you are completing your survey, you will need to take a picture of at least two pieces of trash that you see. Please wear a mask and adhere to social distancing guidelines while completing your trash survey.Remember that honestly and accurately inputting your data is crucial to the work of the Council for Watershed Health. If you are unsure about any part of the data collection process, please revisit the All Drains Lead to the Ocean - Tutorial. If you can't find the answer to your question there, please send me a Canvas message.Step 2: Write a blog postYou will be writing a short blog post (minimum 300 words) that reflects on your experience doing the trash assessments in your neighborhood and explains the importance of monitoring and reducing trash in the environment. This blog post is targeted at a general audience, so you should make it both interesting and informative. In your blog post, you should include the following: A headline that will catch the reader's attention and explain the topic of your blog post clearlyAn engaging introduction that will draw the reader in and make them want to read moreOne or two paragraphs that discuss your experience doing trash assessments and the ways in which your contribution to this CWH trash monitoring project could help the environmentA conclusion with at least one action that the reader can takeThe pictures of the two pieces of trash from your assessmentWhile not required, you are welcome to include additional pictures of your neighborhood or of you completing your trash assessment!Here are some tips for writing an effective blog post:Write in first person. While formal science writing typically avoids the use of "I", you are writing about your experience here and this blog is all about your perspective!Make it personal. Share your thoughts, feelings, and personal experience to help the reader connect to your writing. Keep it interesting. You can include humor, anecdotes, or fun facts so long as they are relevant to your post.Make it straightforward. Keep your sentences and paragraphs short. Your writing style should be conversational and focused - don't include a lot of extraneous information. If you are writing about a complex topic or idea, it is important to write clear explanations and avoid use of too much technical terminology. Make sure to cite any and all sources of information that you use!Here are some examples of good blog posts: Nature in LA (NHM) - L.A. Bats Fight On (Links to an external site.)Nature in LA (NHM) - L.A.'s Street Trees (Links to an external site.)Submission GuidelinesSubmit your blog post by uploading a single file (Word doc or pdf) to this assignment.Note: I will receive separate confirmation from Council for Watershed that you completed your ArcGIS123 survey.GradingTo see how this assignment will be graded, scroll down to view the grading rubric.

1. In this threaded discussion, you will draw on the data you analyzed in the field study. Place your answers to the following questions online. Identify the ecosystem you investigated and state its geographic limits. Write a short summary of the abiotic and biotic factors that you found. In the same post, choose a plant or animal species that is not currently in your ecosystem, and think of a scenario in which this species might realistically migrate into the ecosystem you studied. Describe some of the abiotic and biotic factors in the ecosystem that would affect the species. Do you think this species would become extinct or thrive in your ecosystem? Next read the posts of two or more people. Review and comment on their analysis in a respectful manner. Comment on the parts of their analysis that you find interesting and suggest areas of improvement. In at least two cases for each, explain why you agree or disagree with their analysis. Finally go back to your original post and reevaluate it based on the feedback your peers gave you, and state how other posts changed or supported your initial idea.EXAMPLE ANSWER : Biotic life is plentiful with 2 large trees, many garden plants like small flowering plants, mint plants (Mentha longifolia), earth worms(Lumbricidae), the bugs that live amongst us and my cats. All of these biotic factors assist or retract from one another. One thing I noticed is that because of the large size of the trees, many of the plants are not exposed to sunlight, forcing un-even growth. Forms of energy like rain, sunlight and the water from the sprinkler system, are all included in the Abiotic list.Since we laid new top soil, tended the garden and planted new grass seed, birds have taken notice of the plethora of earth worms in our yard. This has led to an influx of aerial attacks by nearby birds. They have also taken it upon themselves to dwell in the two column like tree that stand in the yard. Look at the illustration of a trophic level pyramid. For each trophic level, write one or two sentences explaining the role of that type of organism. You should include those organisms that fall outside the normal pyramid. Give an example of each type of organism.Your examples do not have to belong to the same food chain in real life. Why does the pyramid get narrower at each higher level? Answer: (8 points) Score 2.  What is an environmental sphere or earth system sphere? Name the earth’s five major environmental spheres and state the defining characteristics of each. Give one example of a way in which two or more earth system spheres interact. Answer: (8 points) Score 3.  What is biogeochemical cycling? For each of the following five cycles, state two processes in which matter changes its form: carbon, phosphorus, nitrogen, oxygen, and sulfur. Answer:

what is partial pressure?
