On this site it provide me with a definition of carbon dioxide.

Since we have been learning about chemical cycles, in my Biology class, this website has been very helpful. This really helped me study for my Biology midterm exam because I was able to have a visual model of what all the chemical cycles looked like. I could go to this site and get a lot of information on the water, carbon, oxygen, and nitrogen cycle. Even though we were taught all of this in class, it helped me to read more information on it so I could have a better understanding on the subject.

The Obama Administration and the EPA have officially announced their intent to cut current coal power plant carbon emissions by forty percent. Experts in the field of power production say that these new regulations are impossible to achieve without extremely expensive prototype-based carbon capture technology. These new regulations will certainly have a huge impact on the cost of electricity in the coming years.

So do you see a parallel to the fire regulations you have been researching? Do you see a similar impact on cost? Will these costs impact in any way the enforcement of these regulations? Do the benefits outweigh the costs?

I found this site to be very helpful. The site provide me with reasonable information that I was interested in. Some of material that I was looking for was what are some of the usage of carbon dioxide.

Summarize: The main points of the Environmental Biology website is to show the five main nutrient cycles: nitrogen, oxygen, carbon, phosphorus and water and how energy flows through ecosystem. The topics covered include: ~the roles of an organism (such as a consumer, herbivores, etc.) ~energy flow through an ecosystem ~food chains and webs/ pyramids and biological magnification ~Humans vs. natural food chains This article goes through the basics of ecology and is very easy to understand. There are pictures of the cycles that relate to the reading. Review and access: This is a wonderful source because it includes all the different nutrient cycles as well as pictures and writing. It also brings up many concepts: bio magnification, the different roles of an organism and human vs. natural food chain. This website doesn't go in depth in a specific part of ecology, but is instead a basic and broad overview of the whole thing. Most websites either only talk about food chains or nutrient cycles, yet this website includes it all. This website is reliable, because I have compared it to other websites and classwork. I would recommend using this website when learning basic ecology or just refreshing your mind because a lot of simple concepts are mentioned. This article won't take long to read, because everything is pretty broad. Reflect: This source was helpful for me when refreshing my knowledge on the water cycle and learning about the oxygen and nitrogen cycle. I have used this site as a notes resource for the ecology unit in my biology class. This site has helped me to better understand the different cycles, the movement of energy through an ecosystem and food chains vs. food webs. ~Riley
