“Acid Rain” Environmental science What is Acid Rain? Acid rain is a rain or any other form of precipitation like rain‚ fog‚ snow‚ or hail that contains harmful substances higher than normal amounts of such as nitrogen and sulfur oxides‚ that is unusually acidic‚ meaning that it possesses elevated levels of hydrogen ions (low pH). Acid rain is also called acid deposition because this term includes other forms of acidic precipitation such as snow. The acid deposition is occurs

Sources of Organic Fertilizers and Amendment Abstract: Fertilizer is one of the most important things for agriculture & crop production. But here we go to discuss about the sources of organic fertilizers. Here we try to inform about different types of organic fertilizer and sources. We also like to discuss here about different structures and functions of organic fertilizer and soil amendment. We show a guide line; by that our farmer can improve production system through organic fertilizers.

algae in the soil (1/2) and mutualistic bacteria in the root nodules of legumes (1). Ammonium compounds in root nodules can be used by legumes to form plant protein (1/2) - lightning / electrical discharge to fix atmospheric nitrogen (1/2) 2) Nitrification (1/2) : by bacteria‚ oxidation of ammonia or ammonium compounds in soil into nitrite (1/2)‚ nitrite into nitrate (1/2) 3) Absorption (1/2) : nitrate absorption into root hairs of a legume by diffusion (1/2) and active uptake (1/2)

91 Chapter 5 Sources of plant nutrients and soil amendments A large number of diverse materials can serve as sources of plant nutrients. These can be natural‚ synthetic‚ recycled wastes or a range of biological products including microbial inoculants. Except for microbial inoculants (biofertilizers)‚ all of these contain one‚ two or several plant nutrients in readily or potentially available forms. A certain supply of mineral and organic nutrient sources is present in soils‚ but

An essay about cycles in biology. Jessie Dean Biological cycles are vital in many aspects of life on earth. From cycles within the body that keep organisms alive such as the cell cycle‚ Krebs cycle and the Calvin cycle to cycles that encompass many aspects of life and our planet such as the Nitrogen and Carbon cycles. The cell cycle involves actively dividing eukaryotic cells passing through a series of stages known collectively as the cell cycle. The two gap phases (G1 and G2) and S (for synthesis)

An ecosystem is a biological environment consisting of all the organisms living in a particular area‚ as well as all the nonliving or abiotic‚ physical components of the environment with which the organisms interact‚ such as air‚ soil‚ water and sunlight. In a typical ecosystem‚ plants and other photosynthetic organisms are the producers that provide the food. (Leibold) Ecosystems can be permanent or temporary and they usually form a number of food webs. Examples of ecosystem include: Marine Ecosystems:
