In the Kingdom Exploration lab, five different organisms were observed under a microscope, (Yeast, Paramecium, Elodea, Daphnia, Euglena). Each of these organisms is apart of one of the six kingdoms, (Eubacteria, Archaebacteria, Fungi, Protista, Plantae, and Animalia) which are apart of three domains, (Archaea, Bacteria, and Eukarya). In this lab, however, none of the organisms observed were archaea or bacteria. Also, all the organisms were eukaryotes, not prokaryotes, which are organisms without a nucleus and a single chromosome (a double-stranded DNA located in an area of the cell) instead. In the lab, organism one is a very small dark green leaf from a small plant. Under the microscope, there is a lot of chlorophyll, floating around inside the rectangular cells. Organism one…
2. Longneck Lagoon is located in Scheyville National Park, 12km North East of Windsor. The national park is made up of 950 hectares of Cumberland Plain Vegetation and it consist of many type of pest plants such as African olive, blackberry and lantana, vines such as balloon vine and bridal creeper etc. There have been over 140 animal species recorded at the park such as vulnerable swift parrot and turquoise parrot and the endangered regent honeyeater.…

The Rio Grande Silvery Minnow is a “small herbivorous North American fish” with “small eyes and mouth”. The diet of the fish is believed to consist of “river plants and benthic macroinvertebrates”, which consists of “small living animals among stones, logs, sediment, and aquatic plants on the bottom of rivers and lakes.” Due to the small size of the fish and difficulty accessing their stomachs, there is “little research into their diet”.…

From August 27th to September 3rd of this year, data was collected from Chaplin’s Lake, Cane River, Wellwoods Lake, and Wellwoods Bayou in Natchitoches, Louisiana. Data collected by previous Ecology classes in 2010 and 2011 was included in the experiment in order to provide data that could help to determine patterns over time. The objective of this experiment was to measure and compare dissolved oxygen content, pH, biological oxygen demand, and turbidity of these four sites in order to determine whether any correlations exist between these factors. Because of the variance between each of the aquatic ecosystems involved in this experiment, each supports different types of plants and animals which are affected by environmental changes such as temperature and, by extension, dissolved oxygen content.…

This experiment was designed to identify the effect of cold-water temperatures on the respiration rate of goldfish. The respiration rates helped to identify the goldfish as being ectotherms or endotherms. Organisms exchange gases with their environment through a process called respiration or breathing. Aerobic respiration, also known as aerobic metabolism, occurs when oxygen is taken into the body and sent to all its cells; the oxygen is then used to break down food for energy (White and Campo 2008). Respiration can be experienced through several structures such as the lungs, tracheae, gills, and integument in order to obtain oxygen. All organisms that experience respiration are either endotherms or ectotherms. Ectotherms are animals that depend on their environment for body temperature. These animals respond to changes in their environment in order to maintain homeostasis, the stable, internal conditions of the organism. Animals that are warm-blooded and can regulate their body temperatures internally regardless of their environment are endotherms. For ectotherms, regulating body temperatures can require more work. Those aquatic animals have adapted several techniques to stay alive. Larry Crawshaw explains that animals, both aquatic and terrestrial, seek to avoid stressful thermal environments or to compensate for the temperature change by mostly lowering the metabolic rate (1979). Lowering the metabolic rate allows certain enzymes to be produced and chemical reactions to happen within the fish that actually warms it up. While lowering metabolic rates are important, respiration regulation is also important. Stephen C. Wood also believes that ectotherms need behavioral mechanisms for temperature control. These mechanisms could include slowing breathing rates to conserve energy and releasing certain chemicals into the body (1991). This…

This paper examines the thermal refuges, effects of coastal storms and winter aggregation behavior on the Florida manatee (Trichechus manatus latirostris). The Florida manatee is a subspecies of the West Indian Manatee (Trichechus manatus) typically found in the subtropical waters of the southeastern United States, feeding on sea grass and freshwater vegetation…
Aquatic and wild animals seem to be a huge contribution of our society and entertainment, but rarely we see incidents recently recalling killer whales at SeaWorld. Reading the article “After Seaworld, ‘Blackfish effect’ on circuses and zoos?” by Kelly Wallace, shows the viewpoint on the topic of the movie called “Blackfish.” The film is about Seaworld and the famous killer whale Tilikum. The history of him and his seaworld experience was introduced. He ended up killing his trainer Dawn Brancheau, and some people even blamed her for it. This is a topic that is rarely discussed in society, but it seems as if people have a misunderstanding or don't know enough about it to have an opinion. The shocking news, is that this is not the first time…
Marine habitats are in grave danger due to humans and Mother Nature. Hurricanes, typhoons, storm surges, and tsunamis are factors in which contributes to the destruction of marine habitats and are caused by Mother Nature. Human’s destruction to these habitats is much worse due to the fact that Mother Nature’s destruction is mostly temporary, while humans leave more of a lasting footprint on the habitats because of our persistence. (National Geographic, n.d.). Marine habitat destruction caused by humans are wetlands being filled for further development, runoff water which carries chemicals, pollutants, and wastes are pumped back into the water without…
One of the most memorable books of my childhood is called “The Rainbow Fish”. In kindergarten, we read this book almost every day. I don’t know why I liked this particular book so much. Was it the colorful pattern the book cover had? I just don’t know. I thought this book was the most amazing book I ever heard of. When I think of this book, I think about how my teacher helped me and my classmates learn how to read better with this book. My literacy experience started at home. Every one can’t say the same. Sitting in bed every night, waiting on my mother to come tuck me in and read me a bedtime stories. When she finally came, she would walk towards my bookshelf to grab a particular book every night. I never knew what it was called, but I know…
This report discusses an experiment to study the rate of aerobic cellular respiration in aquatic organisms which are Elodea (aquatic plant), Snail, and Goldfish, by measuring carbon dioxide production. Because ectothermic organisms (Elodea, snail, and goldfish) were placed in completely covered beaker, each organism would produce different amount of carbon dioxide. The objective of the experiment is to measure carbon dioxide production in three aquatic organisms, and to determine and compare the rate of cellular respiration in each organism. Aerobic respiration is the process which body obtains energy by using glucose + oxygen; this reaction takes place in mitochondrion in a cell; And the result of the reaction are carbon dioxide, water, and energy in the form of ATP ( adenosine triphosphate) (Hoefnagels, 2012). According to Biology 6th Edition, plants use light to convert atmospheric carbon (CO2) into carbohydrate (Johnson, 204). So I predicted snail would respire at the fastest rate and produce more CO2 because its weight was heavier than other two…
