Document Summary

Animals continually exchange heat with their environment. Body heat and temperature determine how well tissues perform metabolically. Animals have developed different ways to maintain adequate body heat. Body warmed by own metabolic processes (mammals, birds) Body is reliant on environmental conditions (reptiles, amphibians, fish) Measure of speed or intensity of random motions within atter. Energy produced by random motions, depends on speed and number of molecules. Some ectotherms can thermoregulate, usually by altering. Temp held in deep body tissues ( approx 37 celsius in mammals,39 celsius in birds) Fluctuates by daily rhythm rather than climate. Temp of outer surface of object or organism. Body mass to surface area ratio is conserved. But requires higher metabolic rate to maintain core body temp in a smaller orgaism. Animals can be classified by thermal categories. 1 - foot bath in ice water. 2- kid bundled up in winter wear. Depends on the environment you are in.
