“It is estimated that the worldwide population of sea otters once numbered between several hundred thousand to over one million before being nearly hunted to extinction by fur traders in the 1700s and 1800s” (Defenders of Wildlife). There are only approximately 106,000 sea otters left. Due to fur trade in the early 1900s, there was once under 2,000 sea otters worldwide. Sea otters can possibly be represented as a poster child for reintroduction yet they still remain on the endangered list. There…

4. Uptake and bioaccumulation of plastic derived chemicals A key factor contributing to the bioavailability of microplastics is their small size, density, color, surface (smooth or rough) (Stephanie L. Wright a,2013). Food chain disturbance in marine environment is the major problem because due to ingestion of plastic which consists of polychlorinated biphenyl (PCB), POP and PAH. They absorbs/bioaccumulation in the fatty acid of living organism and cause death of the species. At least 180…

INTRODUCTION On the 9th our Biology class went on a trip to Sirens Rock Wellington to investigate the organisms living at the rocky shore and their relationships with each other our task was to display information on the relationships between two species we discovered at the Rocky Shore we then use this information to form a report and explain the species and their relationship with one another, but before this we need to understand the definition of zonation; zonation is the distribution of…

carbon 24. Vitamin D3 is produced by ultraviolet irradiation (UV) of its precursor 7-dehydocholesterol. This molecule occurs naturally in the skin of animal and milk. Vitamin D2 is a derivative of ergosterol, which is produced by some organisms of phytoplankton, invertebrates, yeast and higher fungi such as mushrooms. Vitamin D2 is not produced by land plants or vertebrate, since they lack the precursor…

this solution it replenishes all of the animals whilst doing it in a way that won't further damage the environment.By letting nature do its course the way it does best it not only helps all of the endangered animals it also helps the seaweed and phytoplankton. The way it does that…

I interviewed Timothy Beatty who is the dad of my friend Jonathan. I chose him because he works in software engineering, but majored in marine biology while minoring in chemistry and computer science engineering. This intrigued me because in high school I took an oceanography class and fell in love with the study, I wanted to major in oceanography and minor in marine biology, but I figured engineering would be more economic. I still love engineering, so it is not something I’m doing just for the…

An area of coastal wetland that is regularly flooded and drained by seawater is known as a salt marsh. Salt marshes are extremely important to many species as it serves as their habitat, and also saves them from potential predators as only certain species are able to live in the environment of a salt marsh. The salt marsh is mostly shallow and brackish, and consists of mostly saltwater. Salt marshes often develop amid marine and terrestrial environments, which results in biologically diverse…

1. Define introduced species. This is what you would call an invasive animal or species that have infiltrated a different ecosystem than their own. The animals can accidentally or intentionally enter a dissimilar ecosystem. 2. In this Virtual Lab, one of the introduced species did not become a problem to the area. Identify that species and explain why it did not pose a threat to the ecosystem. The experiment with the Tulips and the Vole is the situation that resulted in a non-threating…

increase in CO2 emissions over the past century, other factors have contributed to global warming. One of these is the loss of photosynthetic organisms. This means that organic material that goes through photosynthesis, such as trees, plants, and phytoplankton(plant-like…

opposite side of the spectrum, droughts. Acidification is also harmful to organisms that use calcium carbonate to make shells for protection. A few examples of these organisms include phytoplankton, coral as well as sponges. Acidification would cause a domino effect, for example, if the organisms such as phytoplankton and coral that depended on calcium carbonate would die, then the other species that depended on those organisms for a food source would also die. (eaq.org) Conversely,…
