Algae is an alternative for gelatin and can also be a much more natural/healthier source for creating low carb, gluten and fat-free foods. [4] Algae presents a distinct advantage over traditional food and feed sources, as it does not compete with them and does not require changes in land use.
[44] [45] [55] Additionally, studies have focused on how brown algae growth can be optimized to increase biomass production and therefore increase the quantity of nutrients removed from these ecosystems. [55] Studies have also explored the potential of brown algae to sequester large volumes of carbon (blue carbon). [5] [45] [55]
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
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]
So how does algae become biodiesel? Garton explained the algae has to be grown and cultivated. Afterwards, oil must be extracted from the algae, which can be further refined and turned into biodiesel.
Mucilage mixed with water has been used as a glue, especially for bonding paper items such as labels, postage stamps, and envelope flaps. [7] Differing types and varying strengths of mucilage can also be used for other adhesive applications, including gluing labels to metal cans, wood to china, and leather to pasteboard. [ 8 ]
They enhance water quality by stabilizing heavy metals and other toxic pollutants, as well as cleansing the water of excess nutrients, [26] [2] [1] and lowering acidity levels in coastal waters. [ 27 ] [ 28 ] Further, because seagrasses are underwater plants, they produce significant amounts of oxygen which oxygenate the water column.
Monocots are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf or cotyledon. [12] Terrestrial plants evolved perhaps as early as 450 million years ago from a group of green algae. [13] Seagrasses then evolved from terrestrial plants which migrated back into the ocean.
