Which of the following is NOT true about chemoheterotrophs? Use organic compounds as a source of both carbon and energy Can use light for energy and CO2 as a source of carbon Oxidize organic compounds (e.g., glucose) to generate ATP They are ultimately dependent on autotrophs to provide their carbon and energy None of the other four answers (all are true of chemoheterotrophs)

An organism that gets its energy for ATP from organic molecules and its C from other organisms C.) An organism that gets its energy for ATP from the sun and synthesizes C-C bonds from simple molecules D.)An organism that gets its energy for ATP from inorganic molecules and synthesizes C-C bonds from simple molecules
Which of the following is an organism that obtains its energy from the transfer of electrons originating from chemical compounds and its carbon from an inorganic source such as CO2? photoautotroph Chemoheterotroph Chemoautotroph Photoheterotroph
Most ecosystems on Earth rely on sunlight as the primary energy source for the synthesis of organic compounds that living organisms need. Sunlight does not penetrate deep enough in the ocean to provide energy for organisms living near hydrothermal vents. How can these densely populated communities survive without energy from the sun? A. chemoheterotrophic bacteria convert organic compounds into carbon dioxide which is used by other organisms as an energy source B. chemoautotrophic bacteria harvest chemical energy from hydrogen sulfide and then provide the basis of food for the vent communities C. chemoheterotrophic bacteria harvest chemical energy from hydrogen sulfide and then provide the basis of food for the vent communities D. chemoautotrophic bacteria fix nitrogen which then is used as a source of energy for other organisms
Which of the following types of organisms use an organic source of carbon? a photoautotroph a photoheterotroph a chemoautotroph and a chemoheterotroph a chemoautotroph
Organisms which use light as an energy source and carbon dioxide as a source of carbon are called and organisms which require preformed organic molecules as a source of carbon and energy are called 1.photoheterotroph:chemoautotroph 2. chemoautotrophs, chemoheterotrophs 3. obligate anaerobe; obligate capnophile 4. photoautotrophs; chemoheterotrophs
Match the following characteristics to either (a) autotrophsor (b) chemoheterotrophs:Many microorganisms in this group are infectious.Many microorganisms in this group can carry out pho-tosynthesis.Members of this group usually do not cause disease.Members of this group carry out the same metabolicprocesses as humans.Members of this group break down organic compoundsto obtain energy.Members of this group synthesize organic compoundsto store energy.
Compare photo litho autotrophy with chemo-organo heterotrophy. Sun light is the ultimate source of energy and all living organisms obtain their energy directly or indirectly from the sun. However in deep-sea vents (where there is no sun light) life has originated and the many groups of microorganisms are flourishing in such environment. How? Explain your reasoning
Heterotrophs Group of answer choices cannot produce their own organic molecules (such as sugars) directly. include all plants but only some animals. can convert inorganic molecules such as CO2 into organic molecules. undergo photosythesis but do not undergo cellular respiration.
These enzymes require a temperature of 15 degree Celsius or lower needed for growth / optimal activity. * (Please choose one correct answer only) A. Thermophiles B. Cryophiles C. Halophiles D. Piezophiles
How would radiation at 220 nm affect a microbial cell? It would allow it to photosynthesize. It would allow cells to synthesize vitamin D. It would have little effect, since this wavelength is not easily absorbed by cells. It would cause mutations. It would deactivate photolyases. It would have no effect. This wavelength is absorbed by the atmosphere’s ozone layer.
These are enzymes that can sustain in a high hydrostatic pressure. * (Please choose one correct answer only) A. Piezohiles B. Halophiles C. Acidophiles D. Alkaliphiles E. Thermophiles
