varieties of algae. It can also grow in numerous colors and forms and can be found everywhere on the planet. Many people believe algae is limited to the green film seen on ponds or washed up on beaches, however, that is just a very small portion of what algae is (Sterner, 2013). One of these algae species, and the topic of this experiment, is Chlorella vulgaris. This is a freshwater alga which can be used in wastewater treatment (Gonzales and Bashan, 2000). A significant discussion regarding algae is on
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
rate of photosynthesis in algae beads? Hypothesis Light intensity does affect the rate of photosynthesis. Too much light may cause plants to "burn out" or stop producing oxygen while too little light will not provide enough light for optimal photosynthesis activity and CO2 would stop be taken in and oxygen would stop being produced. Background When using algae beads and a CO2 indicator, the process of Photosynthesis and Cellular Respiration can be measured. In this experiment the intensity of light
Photosynthetic pigments Introduction Some animals and most plants use photosynthesis to convert light energy into chemical energy. The energy that is created can be stored and is accessed later on by consumers. The consumers of the organisms break bonds while digesting the plant material and the stored energy is released into their perspective systems. The entire process of photosynthesis can be summarized as carbon dioxide and water reacting with light to create sugar, water and oxygen. Although
Shannen Lemke 7th period 11/17/17 Light Intensity lab Research Question Does light intensity affect the rate of photosynthesis in algae beads? I was hoping to discover what plants thrive in different lights for future references. I was hoping to find relevant information that will help me make decisions on what plants to purchase. Hypothesis Light intensity does affect the rate of photosynthesis. Too much light may cause plants to "burn out" or stop producing oxygen while too little light
Methods In order to set up the experiment, twelve test tubes total were used; four of them were the control tubes, which had no algae solution contents. The reason for not adding algae is that the control tubes solutions are meant to be the starting point for comparison that has to stay the same throughout the length of the experiment. They are used to set up the blanks on the spectrophotometer (instrument used to measure the amount
Introduction Fossil fuels are the powerhouse to the increasing global need for energy and transportation. Increasing fossil fuel consumption has led to increased prices per unit supply of oil and an increased amount of harmful Carbon Dioxide gas released into the atmosphere (Rawat, Kumar, & Bux, 2012). With growing concern over these affects, many scientists and researchers have come up with a better way to power the globe; by using Biofuels. By switching, the emission of Carbon Dioxide would be
Abstract The purpose of this experiment is to understand the effects of nutrient enrichment and eutrophication, using samples of water from Rio Salado and Encanto Park. The samples will contain different concentration levels of nitrogen, phosphorous and nitrogen and phosphorous combined and the impact it has on algae growth. The results recorded showed that the nitrogen concentration levels had a little change, phosphorous levels had a higher change and phosphorous and nitrogen combined had a
what do Bosmina in the lake eat? Green Algae [7.2 ] Based on your sampling, what do Daphnia in the lake eat? Cyanobacteria [7.3 ] Based on your sampling, what do Trout in the lake eat? Daphnia [ 8 ] When there are not very many individuals of a particular species present, just by chance it is less likely that they will show up in gut content samples. In this lake, Bosmina only eat green algae whereas Daphnia eat both green algae and cyanobacteria. Trout eat BOTH of the
