What are the four most important chemical nutrients for microbial growth? O Carbon, copper, phosphorus, nitrogen O Copper, iron, carbon, sulfur O Carbon, sulfur, phosphorus, nitrogen O Nitrogen, carbon, iron, sulfur

Draw out the Nitrogen cycle; label nitrogen fixation, decomposers, ammonium, nitrates, uptake by plants, nitrogen in the atmosphere, detritus.

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 of the following statements is true of chemoautotrophs? O They use hydrogen sulfide as their hydrogen source for the photosynthesis of their organic compounds. O They "feed themselves" by obtaining energy from the chemical bonds of organic molecules. O They oxidize inorganic compounds to obtain energy to drive the synthesis of their organic compounds. O They live as decomposers of inorganic chemicals in organic litter. O They obtain their energy from oxidizing chemical compounds and get their carbon skeletons from organic compounds.

What happens to our bodies at a cellular level when consume superfood? What are the pros and cons ?

Describe the following metabolisms (photolithoautotroph, chemolithoautotroph, chemoorganoheterotroph, and photoorganotroph)   What is the carbon source for biomass for Autotrophs and Heterotrophs: What is the energy source for Chemotrophs and Phototrophs: What is the electron source for Lithotrophs and Organotrophs:

Fixing free nitrogen from the air means converting into ions that can be used by many types of organisms. O nitrite nitrate Can nitrate be utilized by all organisms? O nitronium O ammonium

Why is energy required for nutrient transport? Give an example of a system that transports nutrients and describe what source of energy is used to move the nutrients into the cell. Why can’t most organisms use the nitrogen gas that is so prevalent in the atmosphere? How do these organisms acquire a usable form of nitrogen?

Why will alcoholic fermentation preserve the nutritive value of fruit juice or grains in the absence of refrigeration? O alcoholic fermentation will lower the pH to -1 thus killing all microbes who would use up the nutrients in the fruit juice of grain the ethanol/alcohol inhibits the growth of spoilage microbes which would destroy the nutritive value of the plant juice or grain O it won't- this is a trick question!! O alcoholic fermentation increases the salt concentration which in turn inhibits growth of spoilage microbes

Microbes which feed on dead organic material are classified as:     pathogens     parasites     saprophytes     autotrophs
