The human population relies on approximately six staple crops and about twenty-four additional crops for our calories. In the United States, nearly 80% of the cropland is planted with one of three species: corn, wheat, and soybeans. What are the remaining other staple crops? What are the risks and benefits of relying on so few agricultural species? Are you concerned about the lack of diversity in agricultural production? Why, or why not? Write at least 250-300 words

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. Use the Lab 5 worksheet for assignment instructions and data collection.

- Never has there been such a devastating or far reaching war as WWII. It was responsible for tens of millions of military casualties and even more civilian deaths. The average age of a WWII veteran is 92. Approximately 413 WWII veterans die each day. Within two decades few if any will still be alive, but its impact on America, Europe, and the rest of the world is incalculable. There are four major fronts during WWII. The colonies (mostly Africa), the western front, the eastern front, and the Pacific. Write a sold paragraph describing the combatants and the impacts in each of those fronts- name the major battles, explain the strategies, and describe the conclusion. Finally, type a paragraph that discusses the greatest consequences of WWII.
