1. How does the plant work? How does it remove solids, reduce organic matter, and restore oxygen to the water?…
●The reactants in light reactions are light and water. The product is oxygen. The Calvin cycle takes in carbon dioxide to make sugar.…
Photosystem I is referred to by the wavelength at which its reaction center best absorbs light, or…
Recent innovation has developed a method called aquaponics. It is a closed system in which water from a fish tank is used to water crops in a hydroponic growth medium. Soil or land is…
This lab is an opportunity to observe, study, and learn about ecosystems and how the environment sustains life but in a much simpler and smaller scale which is called Eco Columns. The environmental conditions in the Eco Column could sustain life for several weeks, therefore over the course of the several weeks we will observe and study the interconnections between each ecosystems. A self sustaining requires components such as energy flow and chemical cycle. This experiment will evaluate our knowledge on the phosphorus, carbon, nitrogen, and water cycle. For example; the water cycle is needed to stabilize the water needs of each organism in the ecosystem; the carbon cycle makes up the living tissues, absorbed by plants through photosynthesis and released during decomposition and organisms breathing; the nitrogen cycle uses bacteria to continue the process of nitrification, roots absorb it, and organisms use it in the form of NO3; the phosphorus cycle are found in rocks which bring nutrients to the soil. In this experiment our goal is to make our eco column the most efficient and make it the ideal environmental conditions for the organism to survive using data, for example we know what levels of nitrite is too high therefore we are going to change the water if the levels of nitrite is too high.…

If you are not a microbe, a human, or an animal, then you are most likely plant. Plants and trees cover about thirty percent of the planet’s surface, as stated in NASA’s Earth Observatory division. They use a process called photosynthesis, which allows plants to take energy from the Sun and later using it as food, as well as producing oxygen through the process of respiration. So how does it happen? The process of photosynthesis occurs as follows.…
Living things get energy to do things through photosynthesis, food molecule breakdown, build up, storage, and lastly cellular respiration. All of these ideas are the reason that myself and others have energy to do anything and everything.…
2. Select the BAR CHART tab. On the graph, notice the Oxygen production bar. Move the Light intensity slider back and forth. How does light intensity affect oxygen production?…
The algae block sunlight to aquatic plants, so photosynthesis slows, and less oxygen is released into the water - low DO levels.…
Fish farming, also known as Aquaculture, is an industry that uses sea life for commercial purposes. One of the most common fish species that are farmed worldwide is salmon. Most of the salmon Americans consume are farmed in British Columbia and grow in open net cages placed directly in the ocean; creating environmental threats in all areas it takes place. The problem with open net cages that are placed directly in the ocean is; the release of ocean harming farm waste, chemicals, and disease. Before these problems can be solved, a look at the salmon net cage industry is needed, along with the environmental impacts.…
