Title: Ecological Interactions of Living Organisms in Beaver Creek Statement of the Problem: How do the organisms in Beaver Creek interact with the biotic and abiotic portions of the ecosystem? The sample was taken from Beaver Creek (a tributary of Tookany Creek) in Glenside, Montgomery County, PA. The pH of the creek was 5.5, and the stream velocity was detectable (greater or equal to walking speed). In the area of collection, the stream width was one meter and the depth was 14 cm. There…

change, "they write (Cullinane.1). As serious as this may seem several damaging effects are happening to the oceans as we speak. The most important creatures in the ocean’s ecosystem like coral are being depleted and overpopulation of photosynthetic algae is going overrun the oceans if nothings done. It needs to be addressed to the public as a serious matter in order produce satisfactory solutions to saving the ocean and the creatures within it. Why should the public care about ocean…

were due to chance or preference. Terrestrial isopods are commonly known as pillbugs, sowbugs, or “roly-pollies”. These organisms are members of the Phylum Arthropoda, Class Crustacea. Isopods are omnivores that generally feed on decaying material, algae, moss and bark. Because isopods respire through gills, they are more restricted to areas with high humidity, particularly under rocks or logs, in leaf…

billions of years however, 1.6bya during the Proterozoic era, we suddenly find the emergence of complex eukaryotic cells. All eukaryote cells share one common ancestor which emerged just once in 4 billion years of life on earth and all plants, protists, algae, animals and fungi are constituted by these cells. The cellular structure of bacteria and eukaryotes are so different there is no evidence to support the ‘directional’ evolution of eukaryotes from bacteria.. Biologists can’t explain…

Organic Chlorella: Great Source of Chlorophyll What is Chlorophyll? Chlorophyll is a component derived from cyanobacteria and from the chloroplasts found in plants and algae. It is an important component for photosynthesis. In the culinary world, chlorophyll is primarily used as a food additive for additional color or for other benefits. Chlorophyll is not water soluble. What Does Chlorophyll Do? There are many claims to the health benefits that chlorophyll present. Humans do not have…

1.Why is biological diversity in seeds important? Biological diversity in seeds important. Certain apples may carry genetic information that causes it to be immune to certain pests. Even though there are many apples that apple is still needed to help prevent pests. 2.Why does Fowler argue that we shouldn't just save the "best" variety of a plant? Fowler argues that we shouldn't just save the "best" variety of a plant because there is no best variety of a plant. 3.Why is climate change an…

AGE, GROWTH & MORTALITY After hatching both Larvae and juveniles are pelagic using the brown algae Sargassum as a transient habitat (Kacem, H., 2015). Sargassum is used by dozens of juvenile species as a relatively safe home for development (Wells & Rooker, 2004). Its presence is constant and reliable throughout their habitats and its size makes it a highly heterogenous environment that allows for the dispersal of each type of juvenile into its own niche (Wells & Rooker, 2004). Once the…

Stormwater runoff brings many problems besides polluting the Bay. It causes a chain reaction of negative events such as killing the native life in the watershed, causing diseases in humans, polluting the air, and loss to the economy. It’s more than simply making the water look repulsive. Stormwater runoff hurts the Bay, and there are simple everyday actions citizens can do to benefit to the Bay. The government can only do so much to protect the Bay. Citizens can build ourselves, volunteer, and…

The book, “Braiding Sweetgrass” by Robin Wall Kimmerer, reinforces the role of humanity and the gratitude we should express towards nature. Moreover, my work makes reference to several of the stories she retells about herself, Native American folklore/culture, and how they connect to science, despite the ways colonization tries to sever it with objectivity and how nature is regarded. My piece begins with a microscope in the center of my work, a reference to a painting in Robin Wall Kimmerer’s…

Introduction: Once a plant begins growth, it depends on multiple abiotic factors to continue growing: light, carbon dioxide and water. These three factors affect the growth rate of a plant, causing it to grow quicker or slower. Furthermore, altering these factors may stunt plants growth or improve it. For example, plants require an adequate amount of water to survive. Water hydrates the plant and also breaks down the minerals in the soil. As the plant absorbs the water, nutrients are transported…
