Algae Covered Pond. Algal nutrient solutions are made up of a mixture of chemical salts and seawater. [1] Sometimes referred to as "Growth Media", nutrient solutions (e.g., the Hoagland solution, along with carbon dioxide and light), provide the materials needed for algae to grow.
Snow algae drive greater changes in snow albedo later in the summer when algae are more abundant. [18] The different abundances of pigments present in snow algae, including chlorophyll and carotenoids, lead to differences in light absorption and therefore albedo changes based on algal community composition. [ 19 ]
Sea ice algae play a critical role in primary production and serve as part of the base of the polar food web by converting carbon dioxide and inorganic nutrients to oxygen and organic matter through photosynthesis in the upper ocean of both the Arctic and Antarctic. Within the Arctic, estimates of the contribution of sea ice algae to total ...
Algae can be used to capture fertilizers in runoff from farms. When subsequently harvested, the enriched algae can be used as fertilizer. Aquaria and ponds can be filtered using algae, which absorb nutrients from the water in a device called an algae scrubber, also known as an algae turf scrubber. [130] [131]
The presence of mucilage in seeds affects important ecological processes in some plant species, such as tolerance of water stress, competition via allelopathy, or facilitation of germination through attachment to soil particles. [13] [14] [15] Some authors have also suggested a role of seed mucilage in protecting DNA material from irradiation ...
During spring and summer, it often seems like your lawn can't get enough water. But once winter temperatures arrive and your landscape quiets down for the season, you may not even think about ...
Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...
Morgan-Peters hurried over to find a separating funnel filled with green-yellow fluid and small chunks of algae. Floating atop the thickest layer of algae was a pale yellow liquid, which Van Kley ...
