Name: Megan RESEARCH REPORTIntroduction Acid Rain forms when sulfur dioxides and nitrogen oxides mix with sunlight, oxygen, and water. It can hurt or damage many things, such as daphnia. Daphnia are from the group called arthropods. Arthropods Adult arthropods have jointed bodies and external skeletons. This exoskeleton may be thick like crayfish or transparent like Daphnia. Arthropods are divided into many groups which are the crustaceans, centipedes, millipedes, insects, and spiders. Daphnia Daphnia are from the group called Arthropods. There are up to 150 known types of Daphnia. Generally they all swim, breath, and eat the same way. Daphnia swim with a jerky motion through the water. (That is how it got its nickname “water flea”. ) Then with a stroking action they move toward the surface. They pause for a while, before the next stroke to the bottom. Daphnia breath from either collecting oxygen from the water or when they capture their food. They eat by using the five pairs of legs inside the body to capture microscopic food. They mostly eat algae, protozoa, and bacteria. After it captures its food it will fall to the bottom of the pond or shallow lake. There are many body parts in Daphnia. Such as the heart that pushes clear fluid around the body. The heart beats from 25-35 times per 10 seconds. The eye is controlled by muscles with nerve connections to the brain. The first and second antennas are used for swimming and sensing the environment. The legs are used for collecting food and balancing the animal as it slowly sinks. The gut is where food particles are digested. They also have a brood pouch for incubating young that hatch from large yolk filled eggs. They have a protective outer shell. Pollution There are many different forms of Pollution. In many large cities automobiles, and factories pollute the air so much that it creates smog. The smog can endanger many people in that area. For an example, in Los Angeles and Mexico City smog is a constant problem. Another form of Pollution is greenhouse gases. This rises miles into the atmosphere, way above the smog. Acid Rain Acid Rain is a dangerous form of pollution. Acid rain occurs when sulfur dioxides and nitrogen oxides mix with sunlight, oxygen, and water. The sulfur dioxides and nitrogen oxides come from burning fossil fuels in power plants, factories, and motor vehicle engines. Acid Rain can damage a lot of things such as forests, lakes/ponds, buildings, animals, cars, and many more things. The things that risk damage are building materials such as steel, paint, plastics, cement, masonry, galvanized, limestone, sandstone, and marble. For these to be replaced costs billions of dollars. Summary Acid Rain can hurt or damage many things. If acid rain kills the daphnia it will cause damage to the food chain for water animals. Also if it damages buildings it will not make that area a very good place to live. ACKNOWLEDGEMENTSI would like to thank the following people for helping make my project possible:
