Which of the following statements is FALSE? A. The addition of phosphorus to polluted coastal ecosystems often results in reduced growth of phytoplankton. B. Shallow marine waters have higher productivity partly because nutrients are easily transported from benthic habitats to surface waters. C. Productivity of marine ecosystems is primarily limited by nitrogen and iron but rarely by phosphorus. D. Rivers tend to have higher primary productivity rates than ponds and lakes. E. Shallow marine waters have higher productivity partly because...

Ecosystems How is food chain different from a food web? Explain the difference between gross primary production and net primary production? What is the role of plant metabolism (respiration) in productivity? Why is energy lost from a food chain? Where does it go? Is it destroyed'? What limits NPP? What patterns exist in NPP in oceans vs terrestrial ecosystems? Are nutrients involved with NPP? Which ones? What trophic level (group of organisms) is needed for every ecosystem? What do the...

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...

Q1. Which type of organism in this lab can get its nitrogen from nitrogen fixation (converting N2 gas into ammonia), allowing it to grow even if easily used forms of nitrogen are not available in its water or food?CyanobacteriaDaphniaBosminaTroutQ2. A company is growing algae in big tanks to make fish food. However, the algae is not growing very quickly, and they suspect either phosphorus, nitrogen, or iron is limiting. What could the company do to figure out which nutrient is...

Define and provide examples of the following concepts: Environment, ecosystem, abiotic and biotic factors, natural and experimental boundaries, flows of matter and energy. Explain how the boundaries of an ecosystem may differ from those like national parks, county, state or national borders. Explain how natural features of the landscape (ex: a watershed) or biological phenomena (ex: a species range) can be used to define the boundaries of an ecosystem. Explain how ecosystems vary in size and scale, and how some...

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...
