Compare and contrast the nitrogen requirements of microorganisms and higher forms of life, describing how their respective requirements are met.© BrainMass Inc. brainmass.com October 25, 2018, 8:35 am ad1c9bdddf
Nitrogen is required for all organisms to live and grow because it is the essential component of DNA, RNA, and protein. However, most organisms cannot use atmospheric nitrogen (N2), the largest reservoir. In fact, over 70% of the air we breathe is composed of ...
The question is a simple problem that is often asked in high school and first year college courses in biology. Why is nitrogen important to microbes and higher organisms? And, how is nitrogen cycled through the environment? The solution is a two paragraph answer that names the processes that are involved in nitrogen cycling. This should provide a start in your quest to understand nitrogen and it's importance.
Industrial & Environmental Revolution. How have they impacted the environment and the way that humans use natural resources?
Describe the Industrial Revolution. How has it impacted the environment and the way that humans use natural resources?
What triggered the Environmental Revolution? When did people become more focused on environmental issues? What are the goals of the Environmental Movement? Do you think that we should continue to pursue these goals? Why or why not?
Biogeochemical cycles describe the cycling and recycling of elements in ecosystems. In your own words, describe the cycling of carbon, phosphorus, and nitrogen through both the living (biotic) and non-living (abiotic) components of ecosystems. And, describe how humans have impacted each of these three cycles.
Questions 1 & 2. Describe the history and importance of the Industrial Revolution, and the Environmental Revolution. What are they? How have each of these impacted the natural environment and our perception of the natural world?
Question 2. There are many good resources that describe these three cycles, including your text, chapter 3. Please develop a one-paragraph summary for each cycle in your own words that briefly describes the cycle. How does each element (C, N, and P) move from the living to the non-living parts of the ecosystem. Then explain how human activity has impacted the natural cycles for each of these three elements.View Full Posting Details
