Assignment: Calculate the Bioaccumulation of The Substance in Your Energy Pyramid Questions

Pyramid Scheme is: Background: In the 1960’s, environmentalists noticed a frightening die-off of bald eagles and osprey. It was believed and later proven to be caused by the insecicide DDT (dichlorodiethyltrichloryleihane). DDT was banned in 1973 in the United States and the numbers of bald eagles and osprey have since increased. Linking the use of which they are naturally found but also the specific organisms in the food chain that inese predators fed upon. in Following this food chain backwards led to a common substance, DDT, which was found to have permeated each level in the chain. Understanding why smaller organisms lower in the food chain might have survived this toxin while their predators were becoming extinct is explained more easily by studying a Pyramid scheme and measuring the amounts of a specific toxin that has accumulated at each level. This acivity seeks to highlight just this type of Occurence. Introduction: Bioaccumulation is the accumulation of a substance in a biological issue. Organisms at any trophic level may be capable of bioaccumulation. Biomagnification is the increasing concentation of a substance up a food chain from one trophic level to the next. Whenever any kind of substance is released into the air, it’eventually seiües on plants. The plants will be consumed by insect herbivores, the primary consumer. When a primary consumer is eaten by a secondary consumer, the secondary consumer is eating the accumulated poison of its prey. The increasing concentraiion of a subsiance up a food chain from one trophic level to the next is called biomagnification. Whenever herbicides or insecticides are sprayed on grass, for example, those poisons are ingested by the animals eating the grass. Because the poisons are fat soluble, they stay stored in the animals faſty tissue. Procedure: doy Grass -4. Teriary 157 chevolins Consumers . 3.

The bottom of the pyramid (producers) begins with grass. Your its second level (a primary consumer) must eat grass. Your topmost level should be your top predator (teruary consumer). You can end either on the third or fourth level.

Suppose the grass that is eaten has been recently sprayed with a pesticide, herbicide or bioterrorism substance. How will ihat substance get concentrated in an energy pyramid? 2. Calculate the bioaccumulation of the substance in your energy pyramid. Your results will be based on what is eaten in just one day. Each blade of grass contains .00003 ppm (parts per million) of a toxic substance. You will need to estimate how much grass your primary consumer eats in one day. Note: Part of the fun of this activity is to think about how much ihese organisms actually eat in a day. If you want to verify your estimates, you might try using a search engine and the Intemet… good luck. eats blades of grass per day x.00003 ppm = ppm.

Important information for writing discussion questions and participation

Welcome to class

Hello class and welcome to the class and I will be your instructor for this course. This is a -week course and requires a lot of time commitment, organization, and a high level of dedication. Please use the class syllabus to guide you through all the assignments required for the course. I have also attached the classroom policies to this announcement to know your expectations for this course. Please review this document carefully and ask me any questions if you do. You could email me at any time or send me a message via the “message” icon in halo if you need to contact me. I check my email regularly, so you should get a response within 24 hours. If you have not heard from me within 24 hours and need to contact me urgently, please send a follow up text to

I strongly encourage that you do not wait until the very last minute to complete your assignments. Your assignments in weeks 4 and 5 require early planning as you would need to present a teaching plan and interview a community health provider. I advise you look at the requirements for these assignments at the beginning of the course and plan accordingly. I have posted the YouTube link that explains all the class assignments in detail. It is required that you watch this 32-minute video as the assignments from week 3 through 5 require that you follow the instructions to the letter to succeed. Failure to complete these assignments according to instructions might lead to a zero. After watching the video, please schedule a one-on-one with me to discuss your topic for your project by the second week of class. Use this link to schedule a 15-minute session. Please, call me at the time of your appointment on my number. Please note that I will NOT call you.

Please, be advised I do NOT accept any assignments by email. If you are having technical issues with uploading an assignment, contact the technical department and inform me of the issue. If you have any issues that would prevent you from getting your assignments to me by the deadline, please inform me to request a possible extension. Note that working fulltime or overtime is no excuse for late assignments. There is a 5%-point deduction for every day your assignment is late. This only applies to approved extensions. Late assignments will not be accepted.

If you think you would be needing accommodations due to any reasons, please contact the appropriate department to request accommodations.

Plagiarism is highly prohibited. Please ensure you are citing your sources correctly using APA 7th edition. All assignments including discussion posts should be formatted in APA with the appropriate spacing, font, margin, and indents. Any papers not well formatted would be returned back to you, hence, I advise you review APA formatting style. I have attached a sample paper in APA format and will also post sample discussion responses in subsequent announcements.

Your initial discussion post should be a minimum of 200 words and response posts should be a minimum of 150 words. Be advised that I grade based on quality and not necessarily the number of words you post. A minimum of TWO references should be used for your initial post. For your response post, you do not need references as personal experiences would count as response posts. If you however cite anything from the literature for your response post, it is required that you cite your reference. You should include a minimum of THREE references for papers in this course. Please note that references should be no more than 5 years old except recommended as a resource for the class. Furthermore, for each discussion board question, you need ONE initial substantive response and TWO substantive responses to either your classmates or your instructor for a total of THREE responses. There are TWO discussion questions each week, hence, you need a total minimum of SIX discussion posts for each week. I usually post a discussion question each week. You could also respond to these as it would count towards your required SIX discussion posts for the week.

I understand this is a lot of information to cover in 5 weeks, however, the Bible says in Philippians 4:13 that we can do all things through Christ that strengthens us. Even in times like this, we are encouraged by God’s word that we have that ability in us to succeed with His strength. I pray that each and every one of you receives strength for this course and life generally as we navigate through this pandemic that is shaking our world today. Relax and enjoy the course!
