Your friend John is having trouble with his compost bin. The material in his compost pile doesn’t seem to be decomposing well. You take a sample of the pile and check for the presence of microorganisms under the microscope. You see that there are indeed microorganisms; however, they don’t appear to be growing very fast. John says that he regularly mixes his compost pile to expose it to oxygen but has noticed the pile feels cold. What is the most likely explanation for this problem?(1 point) Responses The compost pile was placed in the sunshine. The compost pile was placed in the sunshine. The compost pile contained aerobic bacteria. The compost pile contained aerobic bacteria. The compost pile was sufficiently moist. The compost pile was sufficiently moist. The compost pile contained incorrect amounts of "greens" and "browns".
The most likely explanation for this problem is that the compost pile contained incorrect amounts of "greens" and "browns". Proper composting requires a balance of nitrogen-rich "greens" (such as food scraps, grass clippings) and carbon-rich "browns" (such as dried leaves, cardboard). If the ratio is off, the compost pile may not heat up enough to support the growth of microorganisms, leading to slow decomposition.
