8A: Your uncle and aunt are gardening and are putting down organic mulch. They say they heard organic mulch helps with decomposition, how do you explain to them how it works? Select one: a. The organic mulch slows water loss to increase decomposition of undesired organisms. b. The organic mulch slows growth of undesired organisms but also increases their decomposition so the desired plants can grow best. c. The organic mulch slows decomposition of detrital organisms and desired gardening plants. d. The organic mulch is decomposed by detrital organisms that recycle nutrients back into the soils.

Q2.19. All else being equal, in what kind of soil environment would you expect the decomposition rate to be highest? Cool, dry, oxygen-poor Cool, moist, oxygen-rich Warm, dry, oxygen-poor Warm, moist, oxygen-rich Q2.20. Which of the following statements about aerobic and anaerobic decomposition is true? (Hint: Read the statements carefully! The terms "aerobic" and "anaerobic" are so similar that it's easy to misread them.) Aerobic decomposition yields more energy per sugar molecule than does anaerobic decomposition. Anaerobic decomposition is more common when oxygen is abundant in the local environment. Each individual decomposer organism uses both aerobic and anaerobic respiration pathways. Oxidation-reduction reactions occur only in aerobic decomposition, not in anaerobic decomposition.
