Metabolism In Conformers And Regulators Flashcards
3 types of abiotic factors:
Temperature, salinity and pH
The ability of an organism to maintain its metabolic rate is affected by what?
External abiotic factors
Behavioural responses by conformers allow them to do what?
Allow them to tolerate variation in their external environment to maintain in optimum metabolic rate
What is conformers internal environment dependent on?
The external environment
What features do conformers have?
They have low metabolic costs and a narrow range of ecological niches
What do regulators use to control their internal environment?
And what it lead to?
Metabolism
Which increases the range of possible ecological niches
Regulation requires energy for what?
To achieve homeostasis which will increase their metabolic costs
What is a conformer?
Their internal environment is depended upon external environment
What is a regulator?
They maintain their internal environment regardless of external environment
What is the temperature monitoring centre called and we’re is it located?
Hypothalamus located in the brain
Role of hypothalamus?
They bring about corrective responses to return temperature to normal.
Examples of corrective responses to an increase in body temperature:
Sweating - body heat used to evaporate water in the sweat, cooling the skin
Vasodilation - increased blood flow to the skin increase heat loss
Decreased metabolic - less heat produced
Examples of corrective responses to a decrease in body temperature:
Shivering - muscle contraction generates heat
Vasoconstriction - decreased blood flow to skin decreased heat loss
Hair erector muscle contract - traps layer of insulating air
Increased metabolic rate - more heat produced
