How does CO2 Emissions Affect the Ecosystem? Kenyetta Sloan Bryant & Stratton College Ecology Dr. M. McLellan-Zabielski October 24‚ 2012 What would happen if we didn’t cut trees‚ use transportation‚ even turn on our lights or any electrical item we own? Then global warming wouldn’t exist. The things that we do on the daily basis is what produces carbon emissions‚ when we burn oil‚ coal‚ and gas‚ it releases carbon dioxide into the atmosphere.

Interactions and Interrelationships among the Different Components of the Ecosystem I. Introduction Ecology is the study of environmental systems‚ or as it is sometimes called‚ the economy of nature (Hall and Weiss‚ 2010). It studies interactions between different organisms and their environments‚ including relations within its own species and members of others. Ecology focuses more on the population‚ community‚ and ecosystem ecology although it also includes a wide variety of fields. Both

Mikhail Kashtelyan The Consequences of a global temperature rise on arctic ecosystems Nowadays the climate is changing‚ in more exact words the global temperature is raising every year. Those climate changes may cause a lot of different disasters and brake of ecosystems. A place that is really endangered of global temperature rise is arctic. Arctic is a very big icy landmass that is located north of the Arctic Circle. Arctic contains a lot of different kind of species. If the icy landmass
