Thermoregulation fisch
WebbA sensor signal is processed by a control center. The control center triggers a response by an effector (organ or tissue) - a response is a physiological activity that helps return the variable to the set point. Explain the process (steps) of homeostasis as a thermostat. The process is like temperature regulation in a room using a thermostat: 1.

Webb24 mars 2014 · In fish, behavioural thermoregulation involves the selection of a thermally optimal habitat by means of preference and avoidance responses along thermal gradients [4]. The active selection of a given temperature by fish often leads to daily movements between a feeding area and a zone where temperatures enhance growth efficiency [5]. Webb18 sep. 2007 · Maintenance of body core temperature within narrow limits is a major homeostatic function critical for survival.
