unlike the green leaves. Comparing the study to light grown barley and dark grown barley, the null hypothesis for the experiment would be that there is no difference in the pigments found in each. In a second experiment, the TLC and spectroscopy barley results will be compared to other TLC and spectroscopy results of other photosynthesizers like cyanobacteria, red, brown, and green algae. By comparing each to one another, we should be able to find the relative amounts of certain pigments within each
do Bosmina in the lake eat? Green Algae. 7.2. Based on your sampling, what do Daphnia in the lake eat? Green Algae. 7.3. Based on your sampling, what do Trout in the lake eat? Daphnia and Bosmina. 8.1. After reading the above statement, did you miss any species in your gut content sampling? If so, which ones? The specie I missed was cyanobacteria. Exercise 2: P in the Water. 3.1. When the simulation stops, record the population size of green algae (from the graph), and the dissolved
and fresh water.” In the experiment taken in place today we will measure the growth difference of different Ankistrodesmus algae solutions with a fertilizer and salt water. Conclusions and results will depend on what reading and results come as an outcome, we will know if higher salt levels affect positively or negatively to its growth ratio. We know the Ankistrodesmus algae is a freshwater/terrestrial specie from the “algabase” website. We also know that this experiment has been also tried by the

Girard Immanuel Soriano Ecological Principles Lab 9/25/15 Lab Group: I The Effect of C02 Concentration on the Photosynthetic Rate of Algae Introduction: How does the C02 concentration of algal solution affect the photosynthetic rate of Algae? In this experiment, algae solutions of different concentrations of carbon dioxide, on algal growth are tested to determine the effect of varying concentrations of carbon dioxide, on algal growth over a period of nine days. The rate of photosynthesis was
yellow-brownish as shown in figure 8. Plant nutrients, nitrate and phosphate supported production of chlorophyll, increasing rate of photosynthesis. However, excess of these nutrients reduced amount of chlorophyll and photosynthesis stopped. Green Algae formed due to excess of these nutrients which increased competition in terms of nutrient and light energy. (Song et al., 2014)In addition, some leaves received less sunlight which reduced their production of chlorophyll so that time the carotenoid
The Effect of the Great Pacific Garbage Patch on the Ocean’s Plankton and Algae Introduction: The Great Pacific Garbage Patch is the effect of the human population’s waste. The Great Pacific Garbage Patch is a collection of trash floating in the ocean where there is a high density of garbage because of the Pacific Gyre. “Though their name suggests rafts of bobbing refuse, the patches are instead areas with high concentrations of trash — mostly wee bits of plastic particles that have degraded from
cause the biggest problems for plankton and algae. “Plastic also covers the ocean floor, particularly offshore of the large population centers. A recent study from the state of California found that three percent of the southern California Bright’s ocean floor was covered with plastic- roughly half the amount of ocean floor covered by lost fishing gear in the same location.” (Oregon State University News and Communications 70) While plankton and algae are some of the smallest organisms in the Pacific
the Growth of Algae, Chlamydomonas, in a Two Week Culture Introduction: Algae organisms are present in several ecosystems all over the world, including marine, freshwater, and soil environments (WSU Biology Department Faculty, 2017). Their relevant ability to grow in abundance depending on their environmental conditions may prove to be useful knowledge in the event that large amounts of algae need to be grown, such as in its role as a potential biofuel (Liang et al, 2009). Some algae are able to photosynthesize
a Field Experiment • Title: The Effect of Algae Growth on Mud Snails. • Introduction: I am going to do an experiment that will test whether algae effects mud snails. I want to test this because I have learned about the effects of algae on certain ecosystems, and I want to know how it will affect the salt marsh. I am interested in how algae growth will effect mud snails. This project will help me learn the effects of algae on organisms living in the salt marsh. • Question: How does algae affect mud
