Conley, et al.; Science; Vol. 323, no. 5917, pp. 1014-1015, February 2009 This article explores the detrimental effects that anthropogenic nutrients can have on aquatic ecosystems. Nutrients such as nitrogen and phosphorus are vital to many fundamental processes such as protein synthesis, DNA, RNA and energy transfer. These nutrients are needed to support aquatic ecosystems and are key limiting factors. The question the article raises, discusses the detrimental effects that excess amounts of nitrogen and phosphorus can have on an ecosystem. These excess nutrients come from byproducts of urbanization, such as fertilizers, sewage, and other forms of pollution. This problem relates to the balance of a fragile aquatic

Unformatted text preview: ecosystem and would fall under the category of ecology. We can see from this article, the effects humans have on natural ecosystems. Our waste products and industrialization can harm the ecosystem in many ways. This is a problem that can affect the entire food web of an ecosystem. For example, the article suggests that an excess amount of both nitrogen and phosphorus can actually cause eutrophication. Cyanobacterial blooms in lakes and other freshwater ecosystems can deplete oxygen levels (hypoxia) and even disrupt food webs. In order to preserve the fragile aquatic ecosystems and prevent eutrophication, there must be an effort to reduce both phosphorus and nitrogen input into the ecosystems....
