<span>The term “plastics” includes materials composed of various elements such as carbon, hydrogen, oxygen, nitrogen, chlorine, and sulfur. Plastics typically have high molecular weight, meaning each molecule can have thousands of atoms bound together. Naturally occurring materials, such as wood, horn and rosin, are also composed of molecules of high molecular weight. The manufactured or synthetic plastics are often designed to mimic the properties of natural materials. Plastics, also called polymers, are produced by the conversion of natural products or by the synthesis from primary chemicals generally coming from oil, natural gas, or coal. </span>

Eutrophication how can aquatic ecosystems change over time pogil answers
rosijanka [135]
Eutrophication is a process that leads to enrichment of ponds, lakes and any water body with minerals such as nitrogen and phosphorus. Aquatic ecosystems are diverse and consists of phytoplanktons, zooplanktons, fish and other animals. Too much enrichment of the ecosystem adversely effects the flora and fauna of the aquatic bodies. Eutrophication leads to more uptake of oxygen and increases biological oxygen demand of water. With less oxygen available for animals inside the aquatic systems, they might began to die. Eutrophication is a result of human activities and must be minimized for the betterment of aquatic bodies and aquatic animals. Thus, eutrophication might lead to destroy the aquatic bodies over a period of time.
