Answer : option (4) -ecosystems contain only oxidized phosphorus , but nitrogen and sulfur exist in many oxidation states
phosphorus occurs most abundantly in nature as part of the orthophosphate ion (PO4 )3- . while nitrogen exist in different oxidation states like NO2,NO3, NH3 etc sulfur also exist in many oxidation states .
phosphorus is found in nucleic acid as phosphoric acid
nitrogen, phosphorus and sulfur are macronutrients
phosphorus is a limiting nutrient

The sulfur cycle differs from the nitrogen cycle in that Choose one: A. only sulfate, and not nitrate, can be used as an electron acceptor at the end of an electron transport chain. B. only nitrogen, and not sulfur, exists in multiple oxidation states. C. only H2S, and not NH3, is a substrate for photolysis by phototrophs. D. prokaryotes play an important role in nitrogen cycling but not sulfur cycling,

3. Nitrogen Fixation is a process by which some bacteria can convert N2 into ammonia. This process is very important in making the element nitrogen, a component of amino acids and nucleotides, available to ecosystems. Even though N2 makes up 80% of the atmosphere, nitrogen is the limiting nutrient in many ecosystems. Because nitrogen fixation is so energetically expensive, bacteria will only synthesize the proteins needed for this process if there is no available source of already fixed nitrogen, such...

NPP = GPP – R
Net primary production =
______________
= GPP – energy used for cellular respiration
Gross primary production = ________________ production of
primary producers
Respiration = ______________________
Thus NPP is the amount of energy available to primary
consumers = primary production
Explain the different ways in which primary production is
influenced in terrestrial and aquatic ecosystems
Primary production: terrestrial
ecosystems influenced by water, temperature, and
nutrient availability
Evapotranspiration rate measures the amount of
water entering the atmosphere...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
