Document Summary

Heterotherm: bod temp fluc in diff parts of bod (regional) or at diff times (temporal) Radiant heat xchange: e from radiation, uv visible light ir , gain by absorption, lose by re-radiation, direction dep on ani in rela to enviro. Temp diff: larger diff bw ani and enviro = more transfer. Clear night colder bc no clouds, can block radiant heat loss by standing by warm tree or shelter. Dark colour absorb, light reflect, ani change bod colour. Medium: air transparent to radiation, terr ani can absorb from sun, aqua ani cannot directly absorb e from sun bc water absorbs sun e. Ecto absorb heat from rocks and sand, spread bod flat. De(cid:272) sa whe(cid:374) do(cid:374)"t wa(cid:374)t to lose heat. Aqua ani lose heat easily to water, more in water breathing ani bc high sa for breathing high sa for heat loss, ani same temp as enviro, water is heat sink.
