The dunkleosteus is a cast and mold fossil. Fossil remains that have been found are the head plates and neck armor which were excavated in North America, Western Europe, and Northern Africa. They lived nearly 25 million years in the Devonian period. The dunkleosteus is a lot alike to our shark today as both are very aggressive and high on the food chain. When food was short in the ocean dunkleosteus would feed off of each other. The dunkleosteus could grow to be at least 20-30 feet in length and

Lyme Disease Lyme Disease is caused by a bacterium called Borrelia burgdorferi which is transmitted from animals to humans. (1). The means of transmission are arthropod vectors, specifically ticks.

essential nutrients (nitrogen and phosphorus) to their survival (Adlassnig 2011). In order to offset this fact, N. gracilis has adapted the ability to trap its animal prey and obtain those nutrients it lacks in its soil through its prey, consisting of arthropods (mostly ants). As ants climb onto the inner surface of N. gracilis, hoping to capture nectar, the ants slip and fall into the plant’s pitcher which consists of digestive fluids in order to kill its prey (Bauer 2012). Since N. gracilis lives in humid

PREY OR FOOD SOURCE Fire ants consume many types of food. They are omnivores, feeding on sugars (carbohydrates), some oils containing polyunsaturated fatty acids, certain amino acids, and ions in solution. Although they primarily consume other arthropods and honeydew produced by some types of sucking insects (Hemiptera including aphids, scale insects, mealybugs, whiteflies and some others), they will also consume seeds and other plant parts such as developing or ripening fruit, and dead plant or

Literature Citation When writing a research paper, literature citation is important for the following two reasons: (1) to avoid plagiarism (which is against the student code of conduct and is grounds for failing the course) and (2) to assign proper authority to a statement (this adds weight to your paper).

It consumes a wide variety of foods, including grains, seeds, arthropods, and decaying matter, including vertebrate corpses. Like all ants, gracilipes requires a protein-rich food source for the queen to lay eggs and carbohydrates as energy for the workers. They get their carbohydrates from plant nectar and honeydew
