In this process of photosynthesis the algae produce oxygen (O2). On a global scale microalgae produce more than 75% of the oxygen required for animals and humans.
Prochlorococcus and other ocean phytoplankton are responsible for 70 percent of Earth’s oxygen production. However, some scientists believe that phytoplankton levels have declined by 40 percent since 1950 due to the warming of the ocean.
This is how we industrialize algae production when scaled to a maximum volume of 1.5 acre/ft. and an A/V ratio greater than 3.0, output from the system over a 24 hour period is projected to be between 1.5 and 4.0 tons per day depending on species.
Like most plants, many algae produce oxygen during the daylight as a by-product of photosynthesis. At night these algae consume oxygen, but usually much less than was produced during the daylight.
The golden brown blades are like leaves, containing the chlorophyll for photosynthesis. Marine algae are very important to all organisms on earth, as they produce 70 percent to 80 percent of the oxygen in the atmosphere. Giant kelp acts as the ecosystem engineer in the underwater forests off our coast.
In the algae experiments, 20 liters of algae and water (20 kg) spread over eight square meters of lit surface provided all the oxygen for a single person. That’s small enough so you can consider flying it in even a small module, perhaps even a Bigelow inflatable BEAM module would be large enough.
Algae are a very important presence in your pond or aquarium. They, along with other microorganisms like bacteria, help minimize the levels of toxic forms of nitrogen in the water. They produce oxygen. They help stabilize your pond/aquarium.
Algae can be unicellular or as large as a tree like the giant sea kelp. Algae are typically photosynthetic, meaning they need carbon dioxide and sunlight to grow – just like plants.
The primary source of oxygen for a pond is from microscopic algae (phytoplankton) or submerged plants. In the presence of sunlight, these produce oxygen through photosynthesis and release this oxygen into the pond water.
Underwater plants and algae also contribute oxygen during the process of photosynthesis. Photosynthesis is the process green plants use to make sugars, part of the food they need to grow. Dissolved oxygen in the Great Lakes is affected by weather and temperature.
Low dissolved oxygen (DO) primarily results from excessive algae growth caused by phosphorus. Nitrogen is another nutrient that can contribute to algae growth. As the algae die and decompose, the process consumes dissolved oxygen.
The principal components of the atmosphere, nitrogen (78.08 percent), oxygen (20.95 percent), argon (0.93 percent), and carbon dioxide (0.038 percent), occur in seawater in variable proportions, depending on their solubilities and oceanic chemical reactions.
The oxygen attached to CO2 either remains bound to the sugar or is released as water in the Calvin cycle. The net reaction of photosynthesis simply involves the loss of CO2 and the gain of O2. Algae is by far the most efficient photosynthetic organism when it comes to converting CO2 to O2.
Closing Windows Has Virtually No Effect on Oxygen
So changes would be even smaller in most homes. Simply put, humans don’t take in as much oxygen as we think we do. Based on oxygen alone, estimates are that the average person could survive in a completely sealed room for 12 full days!
“A mature leafy tree produces as much oxygen in a season as 10 people inhale in a year.” “A 100-foot tree, 18 inches diameter at its base, produces 6,000 pounds of oxygen.” “On average, one tree produces nearly 260 pounds of oxygen each year.
Algae consume carbon dioxide during photosynthesis, and this consumption is responsible for an increase in pH.
According to Healthfully, algae thrives in water with high pH levels between seven and nine. For most algae growth, an optimum pH is between 8.2 and 8.7. A pH level that is neutral or lower can help decrease the growth of algae.
Contrary to what you may have been told, LED lights do not cause algae growth any more than other aquarium lighting options. … This also discourages algae growth more than anything else—because it’s not the kind of light that causes algae growth, but the intensity of it.
Nitrogen and phosphorus support the growth of algae and aquatic plants, which provide food and habitat for fish, shellfish and smaller organisms that live in water. … Too much nitrogen and phosphorus in the water causes algae to grow faster than ecosystems can handle.
Aquatic organisms need nitrogen to live and can find it in different sources throughout nature. There are two ways a living organism can get the nitrogen it needs: Eat aquatic plants, such as blue-green algae, which take nitrogen from the water and convert it to ammonia or nitrate.
Trees and Carbon Dioxide
Trees, as kings of the plant world, have much more “woody biomass” in which to store CO2 than smaller plants. As a result, trees are considered nature’s most efficient “carbon sinks.” It is this characteristic that makes planting trees a form of climate change mitigation.
ALOE VERA – What’s great about this plant is that it emits oxygen at night time whilst simultaneously taking in carbon dioxide- something we naturally produce when breathing. All this leads to a purer quality of air and a better night’s sleep.
Algae poses a problem to your pond health when you have too much algae overall and during algae blooms. … If your pond has too much plant life, the oxygen levels can decrease to the point that large fish may struggle to survive. An algae bloom is a rapid reproduction and spreading of algae when conditions are right.
Just like plants, providing oxygen for our earth, corals do the same. Typically, deep oceans do not have a lot of plants producing oxygen, so coral reefs produce much needed oxygen for the oceans to keep many species that live in the oceans alive.
Coral, like every living creature, needs food to survive. While the coral themselves need sunlight to produce the sugars and oxygen that sustain them, they also need plankton to help them stay healthy.
Like land plants, seaweed produces oxygen, around 70% of the total oxygen on Earth, and is the basis of the ocean food chain.
