Algae Lab Essay - 695 Words

Jeanine Campa Biology 101 10/20/2010 Ecology-Interspecific Interactions Lab Intro: Ecology is the study of how organisms interact within their environment. Every species interacts with its surroundings, whether it’s within their populations, community, ecosystem, etc. In this lab, we will be comparing two different species and how they grow alone as well as together, in the same environment. More specifically, in this lab, we will be dealing with one of the most important ideas in ecology, the niche. Due to this concept, we can study the environmental circumstances the organism can handle, the essential resources it will need to survive, and how it will obtain these resources. â€Å"Different species can hold similar niches, and the same†¦show more content†¦The carrying capacity determines the population level of a species according to the limiting resources, Algae is one of the most diverse and interesting organisms on the planet. This is because there are over 10,000 unrelated species of organisms that contain chlorophyll and live in large bodies of water or moist land. Keeping a count of population size gives us a good indication of how certain species grow and interact with one another. By using two different species of Algae we can determine what types of interactions the two can encounter. The two species tested were Closterium and Micrasterias algae. We labeled them as species 1 and 2. The purpose of this lab is to determine whether the selected algae species will demonstrate competition or resource partitioning with the coexistence of each other versus alone. At the end of this lab we should be able to determine which species upheld the best under all of these circumstances. Methods: This lab was performed with two different types of algae, Micrasterias and Closterium. Within our groups, we counted how many of each species there were to begin with. Each group sampled one micro liter of each algae stock, five times, and then found the average of the five trials and converted it to milliliters. There were three different test tubes of algae stock containing 100 individuals. The first contained 100 Closterium,Show MoreRelated Diversity of Marine Algae in the Biosphere 2 Ocean Essay1410 Words   |  6 PagesDiversity of Marine Algae in the Biosphere 2Ocean Red algae, Rhodophyta, is easily identified in the marine environment because it appears as a red color. There are many different species, originating from many different corners of the Earth. The ocean biome in the Biosphere 2 was constructed using raw seawater off the coast of Southern California, which contained many different unknown species of algae. During the construction of the biome, other known species of algae from various marineRead MoreExperiments with Algae1205 Words   |  5 Pages INTRODUCTION Spirulina platensis is a filametous blue-green algae (30–70 ï  ­m helix diameter) (Sà ¡ncbez et al., 2003; Tomaselli, 1997). However, It have prokaryotic structure therefore they are a bacterium belong to cyanobacterium (Becker, 2006). Their cell wall contains peptidoglycan in its composition and structure, so it was classified as gram negative (Alessandro Novak, 2010). Spirulina can form population is fresh water and brackish lakes and some marine environments (Belov and Giles, 1997;Read MoreReview Of Botanical Aquatic Science By Ann Burkholder1030 Words   |  5 Pagesmentioned to be the study of algae. When dinoflagellates secrete certain toxins into the water that they reside in, it is known to be called the â€Å"red tide†. Itis also said that an ecologist is someone who studies the functions of nature. Chapter 3 : During her research it is found that the dinoflagellates previously mentioned were present in all the fish born at the Noga lab. It was also seen that the dinoflagellates existed in all the tanks that were present at the Noga labs.

After collecting the sample we placed the sample in a glass jar in the Biology lab at Mid Michigan Community College by a window and then it was sealed with oxygen holes. We would be checking on the sample once a week for lasting six weeks, just incase we miss a week for any reason.

Eutrophication happens when a body of water gets too many nutrients such as phosphorus and nitrogen. These nutrients are fundamental in the growth of a group of single-celled organisms called cyanobacteria, or blue-green algae. When the nutrients in the water are at a normal level, cyanobacteria are normally produced. When the water is overloaded with those same nutrients, however, it can be very harmful. Human interaction is the main reason why these nutrients are beingRead MoreFactors Of Organic Pollution Through The Palmer Index Scoring Method879 Words   |  4 Pagesto the lab. Figure 1.

Fertilizers and sewage are both rich in nitrogen and phosphorus, which are both nutrients essential for plant growth. However, these nutrients are typically low in content in aquatic environments, which limits the growth of algae and plants, but with an increased amount of these nutrients, more plants are able to grow, disrupting the natural environment. Eutrophication is becoming more and more common throughout the world. One main plant growth of concern is that of harmfulRead MoreEffects Of Depth On Algal Growth1891 Words   |  8 PagesLynne Miranda OCB Lab Experiment 04/17/15 The Effects of Depth on Algal Growth in the Biscayne Bay. Introduction Biscayne Bay is located in South Florida and is home to many terrestrial and aquatic organisms. Over the years, humans have populated the land around Biscayne Bay, which has greatly altered the water quality. In a study done in 2011, anthropogenic affects in the bay were measured by testing for an overabundance of nutrients in the water (Carey et al, 2011). This is just one of the many
