Greentumble was founded in the summer of 2015 by us, Sara and Ovi. In the natural process, the ecosystem continuously cycles the matter with the aid of plants and green algae to create a food base for herbivorous and carnivorous from the dissolved chemicals. In the absence of oxygen, the microorganisms capable of living in the absence of oxygen start to decompose organic substances resulting in the release of harmful hydrogen sulphide and ammonia. Eutrophication causes several effects in the marine ecosystem. The oligotrophic water bodies have a rich supply of oxygen, unlike the algae rich eutrophic water bodies. The toxic compounds can also go up the food chain through bio-accumulation and bio-magnification, causing other health complications like cancers. http://www.theaudiopedia.com What is CULTURAL EUTROPHICATION? The bacteria generate a red tide that releases very powerful toxins with high poison levels into the water. Second trophic level: Invertebrates, turtles, and fish are the herbivores. Other sources that contribute to cultural eutrophication include the use of fertilizers, faulty septic systems, and erosion into the lake.
