Of the essential components can affect plant health. Play an important role in the spreading of plant species. Both biotic and abiotic components of a landscape The link between nitrate and nitric oxide is also discussed, along with nitrogen carbon interactions, Nitrogen use efficiency (NUE) and nitrate pollution will also be discussed.Īir, light, water, nutrients, and optimum temperature are vital for plant This chapter elaborates on nitrate assimilation and regulation. The nitrate assimilation pathway initiates with the uptake of nitrate followed by nitrate reduction producing ammonium, which is then fixed into the amino acids, glutamine, and glutamate in most plants. Nitrates remain a major source of nitrogen for all plants because of their versatile functions in both plant nutrition and physiological regulations. Nitrogen is gained by the plant through nitrate or ammonium. Dinitrogen (N2) has to be further processed in order to convert it into a biologically functional variety. Nitrogen is an important component of most of the biomolecules like nucleic acids, proteins, and vitamins. It is then converted into organic components like amino acids by the nitrogen assimilation process. * Offers additional information on a website devoted to further examining critical environmental issues that will help readers make environmentally responsible choices.Nitrogen (N) is a microelement found in the environment in inorganic form. * Includes 'You Can Make a Difference' boxes in each chapter to help readers take an active role in improving the environment. * Presents real-life case studies that offer in-depth analyses of actual situations. * Examines the problems of overpopulation as well as environmental concerns such as air pollution and the pesticide dilemma. * Introduces the reader to ecosystems, the physical environment, and Earth's biomes. It offers solid scientific content balanced with effective and current examples of problems and solutions. Rather than telling readers what to think, the book provides the information and tools they need to reach their own conclusions. The text provides numerous examples and opportunities for readers to explore issues at a local level.Ĭovering the enormous environmental challenges facing our world today, the new fifth edition of The Environment helps readers think critically about these issues and understand the concepts that underlie environmental problems.
