The climate of freshwater biomes is determined by by a number of factors including location, season and depth of water as the most prominent ones (W2). On average the temperatures will decline as the water gets deeper.
America continues to get heavier. An analysis of data collected from 2007 to 2012 has found that 71 percent of Americans are obese or overweight. The picture is slightly worse for men, three-fourths of whom are overweight or obese. About 67 percent of women fall into one of those two categories. In all, nearly 35 percent of Americans are overweight, meaning that they have a body mass index between 25 and 29.9. This metric is a generally reliable way of estimating body fat percentage, though it can overestimate fat in athletes and those with a particularly muscular build.
However, more Mexican women (71%) were obese or overweight than American women. In the US the greatest prevalence of obesity and overweight was found among men aged 50 to 54 (80%) and women aged 60 to 64 (73%). Among Americans under age 20, the greatest prevalence in being overweight or obese was found among children ages 10 to 14, with boys at 38% and girls at 37%.
