Why are energy transfers not 100% efficient?
Why are energy transfers not 100% efficient? The second law explains why energy transfers are never 100% efficient. Because ecological efficiency is so low, each trophic level has a successively smaller energy pool from which it can withdraw energy. This is why food webs have no more than four to five trophic levels. How can […]
Which Kidney stones are the hardest?
Which Kidney stones are the hardest? The calcium oxalate kidney stone comes in two varieties, calcium oxalate monohydrate and calcium oxalate dihydrate. The former are harder and therefore more resistant to fragmentation by lithotripsy. How do you relieve kidney stone pain fast? Over-the-counter pain medications, like ibuprofen (Advil, Motrin IB), acetaminophen (Tylenol), or naproxen (Aleve), […]
How important are energy resources to a human?
How important are energy resources to a human? As the rate of energy consumption continues to grow, competition for dwindling energy resources only makes it more difficult and expensive to keep up the same levels of consumption. One of the reasons that energy resources are so important is that they make it possible for a […]
