ASSIGNMENT INSTRUCTIONS
Greetings!
I need help with a biology essay. The topic is: What is happening to Sea stars in the PNW Shores? This essay requires quality
research and all information must be subject to the Pacific northwest region, specifally Oregon state. Please when conducting
your research use quality sources. I would suggect using like a scholarly or academic database system to conduct your
research. The draft of the essay is due this evening. I will expect the start draft of this essay containing minimum 500
words. I will have you submit this to my by today’s deadline and then you wil continue to work on this essay throughout the
final deadline of March 14th.
This is a Biology research essay so please if you have knowledge of Biology this willl be great for you. I have attached the
essay rubric. Pleass, please pe, read it throughly and understand before you start writing. If you have any questions or require
further explaination please do not hesistate to reach out. Please cite and source all of the material you research and include

I just need a solid 500 words today, so a good introduce and outline of what will be discussed in the essay.
HOW TO WORK ON THIS ASSIGNMENT (EXAMPLE DRAFT/ESSAY)
Introduction:
Sea stars, also known as starfish, are an important part of the Pacific Northwest (PNW) ecosystem. They play a crucial role in maintaining the balance of the ecosystem by controlling the populations of other invertebrates. However, in recent years, sea star populations in the PNW have been declining rapidly, and many have been disappearing altogether. In this essay, we will explore the possible reasons for this decline, specifically focusing on the situation in Oregon State.
Body Paragraphs:
- Sea Star Wasting Disease: One of the main reasons for the decline in sea star populations is the outbreak of Sea Star Wasting Disease (SSWD). This disease is caused by a virus that attacks the sea star’s tissues, causing lesions and leading to eventual disintegration of the animal. SSWD was first observed on the West Coast in 2013 and has since caused mass mortality events in sea stars across the PNW, including Oregon State.
- Environmental Factors: Apart from SSWD, there are several environmental factors that may be contributing to the decline in sea star populations in Oregon. These factors include ocean acidification, pollution, and warming ocean temperatures. These changes in the environment can have a significant impact on sea star populations by affecting their feeding behavior and immune system, leading to a decline in their overall health.
- Predation: Another factor that could be contributing to the decline in sea star populations is predation. Sea stars are known to be preyed upon by various animals, including sea otters, crabs, and seagulls. However, with the decline in sea star populations, the populations of their predators may also be affected, leading to a further imbalance in the ecosystem.
Conclusion:
In conclusion, the decline in sea star populations in the PNW, specifically Oregon State, is a cause for concern. SSWD, environmental factors, and predation are all potential reasons for the decline. It is important to continue monitoring and researching the situation to gain a better understanding of the causes and to take action to protect the sea star populations and the ecosystem as a whole.
