Algal blooms occur due to the presence of an excess amount of nutrients, like phosphorus, in fresh water. How does excess phosphorus get into fresh water? The nutrients are a part of the fertilizers that are often washed away into ponds. The nutrients are added to the water by fishermen to feed the fish. The nutrients leak into fresh water from oil refineries in the vicinity. The nutrients are formed by the decomposition of organic wastes dumped into fresh water.

Figure 46.17 Which of the following statements about the nitrogen cycle is false? Ammonification converts organic nitrogenous matter from living organisms into ammonium (NH4+). Denitrification by bacteria converts nitrates (NO3-) to nitrogen gas (N2). Nitrification by bacteria converts nitrates (NO3) to nitrites (NO2-). Nitrogen fixing bacteria convert nitrogen gas (N2) into organic compounds.
Plants obtain ______ by taking it up from the air. a. nitrogen c. phosphorus b. carbon d. water
Why do raw household ingredients such as granulated sugar and cooking oils never go bad in normal conditions? Extrinsic factors (room temperature) These foods have a very low Aw ph of these ingredients is too low to support spoilage organisms They do spoil
Plants absorb dissolved nitrates from soil and convert them into : Free nitrogen Urea Proteins Ammonia
In your environmental science lab, you test water samples from local bodies of water and find high levels of coliform bacteria. What does this tell you the water is contaminated with? Inorganic fertilizers O Household chemicals Oil Animal waste O Arsenic
How does water pollution affect the Phosphorus, Carbon, and Nitrogen Cycles? My question is how does water pollution affect the Phosphorus, Carbon, and Nitrogen Cycles, not how does the phosphorus, Carbon, and Nitrogen Cycles cause water pollution. Please answer the question correctly.
In the diagram below, which letter represents the process of denitrification? OOOO BECO D NO, N₂, N₂O A NO3 D E NO₂ ary producers N₂ B NH4+ m Animals Detritus C
Which of the following statements is not true about bioremediation and biodegradation? Microbes played a critical role in metabolizing the crude oil in the Deepwater Horizon spill in the Gulf of Mexico. Oil-degrading microbes have enzymes that use molecules in the oil as substrates. Phosphorus and nitrogen stimulate the growth of oil-degrading microbes. dding easily metabolized organic matter such as glucose increases biodegradation. The biodegradation of plastics is fast because of their chemical structure and properties.
Which nitrogen flux is incorrectly described? O nitrification is the conversion of ammonium to nitrates nitrogen mineralization is the conversion of organic nitrogen to inorganic nitrogen nitrogen immo bilization is the conversion of ammonium to metamorphic rock O denitrification is the conversion of nitrate to nitrogen gas O nitrogen fixation is the conversion of nitrogen gas to bioavailable forms of nitrogen
Match the following biogeochemical cycles terms to the correct definiton. In this cycle the absorption of this 1. bio-essential element from the atmosphere increases the pH of the oceans. The main reservoir of this nutrient 2. is in the building block for all necessary biomolecules (fats, proteins, and carbohydrates) that constitute an important part of the inorganic matter. The element of this cycle is stored 3. in long-term in Carbonate rocks (e.g., limestone) And Fossil carbon (e.g., oil, coal) SInk The material flows in from the 4. reservoir. Source The reincorporation of this 5. element in its cycle is slow Carbon cycle because a considerable amount of it is stored in animal epidermal Phosphorus cycle alpha-keratin protein filaments. In this cycle the fungi from 6. the Rhizobium family helps in the Nitrogen cycle fixation of this element into the soil. Most plants cannot access this 7. nutrient from the atmosphere; therefore, they obtain it from the soil. This cycle refers to a 8.…
