A) How do the controls over NEP and NECB differ from the controls over GPP and decomposition? Why are these controls different? (Chapter 7)
Net ecosystem carbon balance (NECB) is the net rate of carbon accumulation by an ecosystem. It is the change in ecosystem carbon stock over time. Net ecosystem production (NEP) is the total amount of carbon moving into an ecosystem minus the total respiration of the ecosystem (GPP-Recosytem). Where gross primary productivity (GPP) is the sum of all photosynthetic activity measured at the ecosystem scale. Decomposition is the conversion of dead organic matter into CO2, mineral nutrients, and organic compounds through the processes of leaching, fragmentation, and chemical alteration. All of these concepts are interrelated and fit into NECB, but the controls differ in some substantial ways.
GPP is controlled by amount of photosynthetic tissue, the duration of the activity (including environmental stressors), and soil resources (water and nutrients). This represents the largest carbon flux into the system and one of

Fungi typically have a suite of different enzymes capable of breaking down different types of plant compounds (lignin, cellulose, etc.). On the other hand, bacteria and archaea may only produce one or some of the necessary enzymes to break down these same compounds. In order for bacteria to break down those more complex compounds they have to form a consortium where each contributes a particular enzyme, each of which contributes to breaking certain bonds within those compounds. For example, cellulose breakdown requires a suite of three different enzyme systems: endocellulases break down the internal bonds, the exocellulases remove the ends of the chains, this forms cellobiose, which can be absorbed, but is further broken down by cellobiase intercellularly to create
Being accepted into the National honors society is not only and honor, but most importantly a privilege. This means that I have achieved many academic goals, such as my 3.86 GPA, and success in many of my other clubs as well. I have taken multiple honors classes throughout high school and excelled in them. They have taught me a strong positive work ethic and gave me the criticism that I need to better myself. Also, I have been given the responsibility as Captain of my golf team. My job is to instill confidence and inspiration to my teammates ensuring them that they can accomplish the highest of goals on the golf course. Not to mention that is only one of my leadership rolls at Middletown High School South.
One major difference is that fungal cells have cell walls that contain chitin, unlike the cell walls of plants, which contain cellulose.The chitin adds rigidity and structural support to the thin cells of the fungus, and makes fresh mushrooms crisp
National Honor Society truly is a honor to be accepted into. National Honor Society represents scholarship, leadership, service, and character. I believe since I was young I have shown compassion and leadership needed in our society. That is why this is the right society for me.
Volunteering, in minor or significant ways, taught me that I could make an impact in the world and along the way build my character, experience the world, and develop better communication skills. I learned this at my local library, Fumo Family Branch. I aspire to become a part of the National Honors Society because I want to network with my peers and people outside of the Academy at Palumbo, improve my character and leadership skills, and give back to my community. I strongly believe that I am a great candidate because I possess the four pillars of the National Honors Society: scholarship, character, leadership, and service.
The biosphere has radically increased in pollution since the start of the industrial revolution (Nriagu, 1979). Global industrialisation has polluted soils and water systems worldwide (Manousaki and Kalogerakis, 2011), which has had significant consequences on ecosystem stability (Uzu et al., 2011; Schreck et al., 2012; Shahid et al., 2013; Pourrut et al., 2013). Infrastructure development is generally accompanied by environmental degradation, because the rate at which waste is built up is not effectively dealt with. This has caused the pollution is from industrial waste to be the
I am very grateful for the opportunity to apply for membership to the Anselmo-Merna National Honor Society. I am excited to take on a greater leadership role in my school and community. The National Honor Society is known for creating individuals that will strive to show exemplary character in and out of the classroom now and for future years to come. Scholarship is one of the four very important pillars of National Honor Society. I believe I should be accepted into the National Honor Society because I work very hard to maintain my 3.5 GPA. and have stayed consistently on the Honor Roll since the seventh grade. I am very diligent about my schoolwork and I always do the best work possible. I enjoy learning new things and trying to better cultivate
Throughout the past four years of high school, I have done my best to try and stay actively involved in the community. I have been presented with some amazing volunteer opportunities such as Huron Safety Town, STAR Leadership Camp, American Red Cross, and Huron High School Girl’s Basketball Biddy Program. I spent over 24 hours at Huron Safety Town where I was able to help young students, mainly those going into Kindergarten, learn how to stay safe while on the road. I was also able to spend over 24 hours at STAR Leadership Camp where I was a councilor to those going into the sixth grade. I made sure that each student understood the importance of being a leader in today's society and how important they are to Huron’s community. Through National Honor Society I have been able to maintain in constant contact, approximately 10 hours, with the American Red Cross by volunteering in monthly blood drives. I have also dedicated 16 hours of my time to those young girls interested in someday being a varsity basketball player through the Biddy Basketball Program.
I am interested in being a part of the GNS Research Program because of my love for science since a very young age. Ever since my introduction to science in elementary school, I have been drawn by multiple subtopics within it. My especial passion for outer space began only recently, in the spring of 2016. I think of the space outside of humanity’s knowledge as endless and deep, full of discoveries waiting to be discovered. I recognize that outer space itself is a broad topic, leading me to favour certain aspects of it, including extraterrestrial life. One example of pursuing the research of extraterrestrial life, or aliens, is in my English Passion Project, where I presented a logical, scientific side and a conspiracy-like side as well as

Q1. Explain how the corporate guided market mitigates the threat of under-consumption in the system of abundance.
Lignin is composed of non-phenolic and phenolic structures. White-rot basidiomycetes such as Phanerochaete chrysosporium, Trametes versicolor, Trametes Trogii, Pleurotus ostreatus, Lentinula edodes, Irpex lacteus, Fomes fomentarius and Cerrena maxima have been found to be the most efficient lignin-degrading microorganisms studied. It has been reported that lignin degrading fungi secreted enzymes collectively termed “ligninases” (Figure 2). These include two ligninolytic families; phenol oxidases (laccases) and peroxidases [lignin peroxidase (LiP), manganese peroxidase (MnP) and versatile peroxidase (VP)]. In delignification process, ligninolytic enzymes have been applied in different methods as fungal delignification, enzymatic delignification, laccase-mediator system (LMS), and integrated fungal fermentation (IFF) (Angel, 2002; Martin, 2002; Pérez et al., 2002; Alcalde, 2007; Hammel and Cullen, 2008; Plácido and Capareda, 2015). Lignolytic peroxydases
All the carbon released into our atmosphere contributes to the rise of greenhouse gases. The carbon from costal ecosystems is referred to as Blue Carbon. Most of the carbon on Earth is cycled through the ocean and coastal areas. These wet environments help to contain carbon and slow the increase of green house gasses in our atmosphere.
