The idea is that mice and birds have a low metabolic rate (less than 0.5 Watt) and low mass (less than 100 g), and at the other end of the scale, elephants have a much higher metabolic rate (more than 1000 Watts) and a higher mass (more than 1000 kg). Most animals fit quite closely to the line between those 2 extremes, on the log-log scale. <\/p>\n<p class=\"alt\"><a href=\"#respond\" id=\"comms\">Be the first to comment<\/a> below.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><a href=\"https:\/\/www.intmath.com\/blog\/videos\/friday-math-video-the-surprising-math-of-cities-and-corporations-6364\"><img loading=\"lazy\" alt=\"Math of Cities\" src=\"\/blog\/wp-content\/images\/2011\/07\/math-of-cities.jpg\" title=\"Math of Cities\" width=\"128\" height=\"100\" class=\"imgRt\" \/><\/a>This video discusses some of the reasons - and solutions - for global warming.
