Nitrogen fixation

Take Home Final Exam 1. a. In my experiment there would be three experimental groups: the first would have both nitrogen (N) and phosphorus (P), the second would only have N, and the third would only have P; all three groups can be tested in order between April and mid-June where the graph shows the lake had some of the highest biomass of Diatoms, Dinoflagellates, and Green algae. The independent variables would be the N and P in each experimental group and the amount added in each setting;…

evoked purely through the act of host lysis, but very few studies have considered the chemical contributions of the viral particles themselves. Recent studies show that the marine virus particles contain significant amount of macronutrients (Carbon, Nitrogen, Phosphorous) and that the…

The nitrogen cycle is the biogeochemical cycle by which nitrogen is converted into multiple forms as it goes by among the atmosphere, terrestrial, and marine ecosystems. These cycle can occur throughout the biological and physical processes. The five main processes of the nitrogen cycle through the biosphere, atmosphere, and geosphere includes the nitrogen fixation, assimilation, nitrification, ammonification, and denitrification. Many…

The illustration above is a good summary for the people who have knowledge about Chemistry, Biology, and Geology. However, it is challenging to understand for people who do not have knowledge in the fields mentioned above. It is so important to give an interpretation so that those people can understand this report. Photosynthesis: This is the process by which plants create their own nutrient by using sunlight. Sunlight acts as the convertor to transform carbon dioxide (CO2) into organic…

which is measured by the plants yield. One of the major limiting factors of plant growth is nitrogen (Franche, et al., 2009). To convert nitrogen into a suitable form for plants to use, molecular nitrogen is reduced to ammonia by a biological process known as nitrogen fixation (Franche, et al.,…

Symbiosis is a crucial part of our existence and a reason for the beginning of life on this planet we call home. According to history of our planet, Earth was formed from absolute nothingness to tiny molecules of thick water vapor and many compounds of nitrogen, carbon dioxide, ammonia, and more. From these molecules, the disorder and order of the molecule reacted with each other, creating and forming the first cell. Millions of years later, these cells created atmospheric oxygen. During the…

they changed the mixture of gases in our atmosphere, hence resulting in a dramatic increase of acid rain levels. Pollution and burning of fossil fuels are the main causes for acid rain. These human activities cause the release of compounds such as nitrogen oxide and sulfur dioxide…

and other disturbances. Nitrogen fixation: Nitrogen fixation is an essential function of microbes in forests. Without bacteria, which are capable of converting gaseous nitrogen into nitrates, and nitrites, which plants can utilize, rainforest soils would rapidly become depleted of this essential mineral in usable form. Many million tons of nitrogen are converted annually and added to the soil by these organisms. In the many tropical soils which are nutrient-poor, only nitrogen-fixing bacteria…

in the face of exponential population growth. In class we studied five ecosystems that were vital to resource sustainability and the continuance of life on planet earth. These five cycles we studied were: the water cycles, the carbon cycle, the nitrogen cycle, the phosphorus/ rock cycles, and the sulfur cycle. First I will describe how the water (hydrologic) cycle contributed to resource sustainability and to continue…

the microbe internally* (V. Clarke et al 2014). The symbiotic relationship between plants and fungi is an essential one for benefiting fully from Mycorrhizae, which then helps the land plants absorb the essential nutrients such as phosphorus and nitrogen. The interaction between plants and microbes allows for essential functions of the plants such as growth, germination and health of the plant, as well as for helping the plant fight off disease and stress. The beneficial fungi being present will…
