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.
The increase in obesity rate is accompanied by a slight decline in the percentage of Americans classified as normal weight or as overweight but not obese. The percentage of normal weight adults fell to 35.3% from 35.9% in 2012, while the percentage of adults who are overweight declined to 35.5% from 36.1% in 2012. An additional 1.9% of Americans are classified as underweight in 2013 so far.
