Title: Identifying Environmental Hazards

Instructions:You will write a 1-page lab report using the scientific method to answer the following questions:

· Why do you see increases and decreases in the invasive species population?

· What are the implications associated with these alterations to the ecosystem as a whole?

Part I:Using the lab animation, fill in the data table below to help you generate your hypothesis, outcomes, and analysis.

Part II:Write a 1-page lab report using the following scientific method sections:

Purpose
State the purpose of the lab.
Introduction
This is an investigation of what is currently known about the question being asked. Use background information from credible references to write a short summary about concepts in the lab. List and cite references in APA style.
Hypothesis/Predicted Outcome
A hypothesis is an educated guess. Based on what you have learned and written about in the Introduction, state what you expect to be the results of the lab procedures.
Methods
Summarize the procedures that you used in the lab. The Methods section should also state clearly how data (numbers) were collected during the lab; this will be reported in the Results/Outcome section.
Results/Outcome
Provide here any results or data that were generated while doing the lab procedure.
Discussion/Analysis
In this section, state clearly whether you obtained the expected results, and if the outcome was as expected.
Note: You can use the lab data to help you discuss the results and what you learned.
Provide references in APA format. This includes a reference list and in-text citations for references used in the Introduction section.

Give your paper a title and number, and identify each section as specified above. Although the hypothesis will be a 1-sentence answer, the other sections will need to be paragraphs to adequately explain your experiment.

Purpose

The purpose of this lab is to determine the hazards that are pressing on our environment.

Also I am going to help us understand why the evasive species keeps rising and decreasing.

Mussels are a wonderful species and most do not understand how they appeared in America, this

is another purpose for this paper.

Introduction

The rise and decrease of Mussels are caused by cargo ships. When cargo ships leave

their port they must fill their empty ballast tanks with water. When the ships reach their

destination they must dump the tanks to pick up their cargo. These cargo ships repeat this

process and have been since 1959, ever since the St. Lawrence Seaway opened.

Hypothesis/Predicted Outcome

These mussels will continue to rise and fall without any hesitation. This is not a threat in

my view. There is a lack of effective predators and pathogens to help keep their numbers

regulated. I had no problem acquiring this outcome with the use of the M.U.S.E. link which was

provided to use.

Results/Outcome

When I watched and read the information on the link which was provided, it helped me

clarify my outcome as I stated earlier. These mussels are no threat to us or our environment

instead they helped America move forward with succession.

Assignment Description

Student Instructions

For each assignment, you will use the M.U.S.E. link to complete the lab. Access the M.U.S.E. by clicking on Learning Materials.

In this lab, you will determine how an invasive species—the zebra and quagga mussel—affects other species in the freshwater lake.Use the animation to help you come up with an answer to the following:

Why do you see increases and decreases in the invasive species population?
What are the implications associated with these alterations to the ecosystem as a whole?
The Effects of Zebra and Quagga Mussels Introduced into a Freshwater Lake

As you have learned, population dynamics are caused by the biotic potential of the population and the effects of environmental resistance. When there is minimal environmental resistance impacting a population, it will exhibit a population explosion. One reason for minimal resistance could be factors that no longer regulate a population (e.g., predator decline or resource increases). Another reason for a population explosion is the introduction of an invasive species. Invasive species are species foreign to an ecosystem and are not immediately regulated by the environmental restraints of the particular ecosystem that they invade. This in turn allows their populations to grow seemingly uncontrolled and to displace other indigenous populations. Examples of such an invasive species into North America are dreissenid mussels, commonly known as zebra and quagga mussels. Their introduction into the Great Lakes has caused economic hardship and a reorganization of the ecosystem. This has led, in part, to pollution-causing effects that can be linked to an alga known as Cladophora.

Ecosystems are webs of intricately balanced interactions, what happens when a new species is introduced that uses a disproportionate share of the ecosystem’s resources?

Using the M.U.S.E. link, review the background information and animation to complete your report.
