2.4 Flashcards
Name abiotic factors that affect the metabolic rate of an organism
Temperature, salinity, pH
What is a conformer?
Organism with a low metabolic rate that rely on abiotic factors and use behavioural responses to maintain optimum metabolic rate.
Describe the meaning of a metabolic cost for a conformer
They use low quantity of energy as they don’t rely on physiological mechanisms.
What do conformer use to maintain their metabolic rate
They use behavioural response to adjust to external conditions
What’s so disadvantageous about being a conformer
Restricts them to a narrow range of ecological niches and less adaptable to change.
What’s the difference about abiotic factors that helps regulators work?
They can alter their metabolic rate and maintain a steady internal environment and don’t depend on abiotic factors.
What’s so advantageous about being a regulator?
Wide range of ecological niches, more adaptable due to changing their metabolism.
What’s a disadvantage about having a high metabolism .
Higher metabolic cost, require more energy to achieve homeostasis.
What is homeostasis?
A physiological response in order to maintain an organisms internal environment.
What is brought about by negative feedback control.
Homeostasis.
What is negative feedback control?
A body’s internal environment changes from its set point. Body responds to return back to the set point.
