YEAH GOT 100 ON THE QUICK CHECK
To answer these questions, you can use your knowledge of the nitrogen cycle and the roles of different organisms within it. However, if you are not familiar with the topic, you can also use external resources like textbooks or online research to find the answers. Here's an explanation for each question:
1. Which organisms are capable of converting gaseous nitrogen in the air into a form that other living organisms can use?
To answer this question, you need to know which organisms have the ability to convert gaseous nitrogen in the air (N2) into a usable form like ammonia (NH3) or nitrate (NO3-). The correct answer is A. Nitrogen-Fixing Bacteria. Nitrogen-fixing bacteria can take nitrogen gas from the air and convert it into a form that can be used by plants and other organisms.
2. Which step in the nitrogen cycle is accelerated at the beginning of the eutrophication process?
To answer this question, you need to understand what eutrophication is and how it affects the nitrogen cycle. Eutrophication is the process by which a water body becomes enriched with nutrients, leading to excessive plant and algae growth. This can lead to oxygen depletion and harm other organisms in the ecosystem. The correct answer is B. Nitrogen Fixation. In the beginning stages of eutrophication, there is an increase in nutrient availability, including nitrogen. This stimulates the growth of nitrogen-fixing bacteria, accelerating the nitrogen fixation process.
3. Which of the following is carried out by denitrifying bacteria?
To answer this question, you need to know the function of denitrifying bacteria in the nitrogen cycle. Denitrifying bacteria convert biologically useful nitrogen compounds (such as nitrate) back into gaseous nitrogen (N2), completing the nitrogen cycle. The correct answer is C. Convert biologically useful nitrogen to gaseous nitrogen.
4. Which type of organism moves nitrogen from cells of producers back to the soil?
To answer this question, you need to understand the role of different organisms in returning nitrogen back to the soil. Decomposers, such as bacteria and fungi, break down dead organic matter and return nitrogen to the soil in the form of ammonia or nitrate. The correct answer is A. Decomposers.
5. What would be the consequence of an ecosystem that had no nitrogen-fixing bacteria?
To answer this question, you need to think about the importance of nitrogen-fixing bacteria in the nitrogen cycle. Nitrogen-fixing bacteria are crucial for converting atmospheric nitrogen into a usable form for plants and other organisms. Without them, plants would have limited access to biologically available nitrogen. The correct answer is C. Plants would have to rely on biologically available nitrogen present in the soil.
