user: Please answer this: Given the background: Compared to conventional milk production, organic milk production tends to have lower eutrophication potential per ton of milk or per hectare of farmland, because it potentially reduces leaching of nitrates (NO3−) and phosphates (PO4−) due to lower fertilizer application rates. Because organic milk production reduces pesticides utilization, it increases land use per ton of milk due to decreased crop yields per hectare. Mainly due to the lower level of concentrates given to cows in organic herds, organic dairy farms generally produce less milk per cow than conventional dairy farms. Because of the increased use of roughage and the, on-average, lower milk production level per cow, some research has connected organic milk production with increases in the emission of methane.Animal welfare issues vary among dairy farms and are not necessarily related to the way of producing milk (organically or conventionally).  and the situation: Robert and his brother Dale are both dairy farmers that primarily produce milk products. Both Robert and Dale have farms that approximately the same size. Dale prefers to produce milk conventionally, as he likes the way that conventional milk tastes. Robert, on the other hand, decided to switch to organic milk production after reading an article online about it.  Answer the following question: Whose farm, Robert's or Dale's, will have lower eutrophication potential?
++++++++
Answer: Robert's


Please answer this: Given the background: The intentional cultivation of arthropods and other small animals for human food, referred to as minilivestock, is now emerging in animal husbandry as an ecologically sound concept. However, the greatest contribution of arthropods to human food supply is by pollination. Three-fourths of the world’s flowering plants and about 35% of the world’s food crops depend on animal pollinators to reproduce and increase crop yields. More than 3,500 species of native bees pollinate crops. Some scientists estimate that one out of every three bites of food we eat exists because of animal pollinators, including birds and bats and arthropods like bees, butterflies and moths, and beetles and other insects.  and the situation: Two villages had many inhabitants practicing horticulture. People from Valley village grew flowers and used arthropods and other insects for pollination and crop protection. Granite village used arthropods and snails, they cultivated them for food.  Answer the following question: Which village cultivated no arthropods for food?
++++++++
Answer: Valley


Please answer this: Given the background: They feed on living hosts. As parasites , fungi live in or on other organisms and get their nutrients from their host. Parasitic fungi use enzymes to break down living tissue, which may causes illness in the host. Disease-causing fungi are parasitic. Recall that parasitism is a type of symbiotic relationship between organisms of different species in which one, the parasite, benefits from a close association with the other, the host, which is harmed.  and the situation: Two frogs are being examined in a laboratory. Frog X was found in a pond in the forest and has a parasite in it. Frog Y was found just outside the laboratory and is missing one eye. The employees at the lab weren't planning on analyzing any frogs, but when they found the one outside their front door they changed their mind.  Answer the following question: Which frog is less likely to contract an illness?
++++++++
Answer:

assistant: Frog Y
