Biogeochemical Cycle Essay

The Biogeochemical cycle is defined as the natural way essential elements such as nitrogen, carbon etc. are circulated within the nature. It is referred to as a biogeochemical cycle due to the biological, chemical and geological nature of each cycle.

In other words, the ways in which elements move between its various living and nonliving forms and regions within the biosphere is called a biogeochemical cycle. Biogeochemical cycles such as nitrogen& carbon cycles are important to living organisms.

Nitrogen Cycle

Nitrogen is an essential element in the bodies of living organisms. Nitrogen atoms are found in all proteins and DNA. Nitrogen exists in the atmosphere as N₂ gas. In nitrogen fixation, bacteria convert N₂ into ammonia a form of nitrogen which is usable by plants. When animals eat the plants, they consume the nitrogen compounds. Nitrogen is a common limiting nutrient found within the nature, and agriculture. A limiting nutrient is the nutrient generally limits the growth. When fertilizers containing chemicals such as N₂ and P₂ are carried into sea bodies, they can result in blooms of algae and this is called eutrophication.

Algae and microorganisms consume large quantities of oxygen for cellular respiration during the night time and hence eutrophication

Most of these are unknown, however we do know about E. coli, which is one of the normal bacteria found in all human large intestines. Humans consume food which provide E. coli with food they want and also and a place to live. In return, these bacteria’s vitamin K and make it harder for pathogenic bacteria to establish themselves in our large intestine. Even though most of the species of bacteria found in our digestive system aid in digestion, absorption, or vitamin production isn't completely known, they all make it harder for invasive pathogens to establish a foothold inside us and cause
