Topic 4: Metabolism in Conformers and Regulators Flashcards
What effect can external abiotic factors have won an organism?
The ability to maintain its metabolic rate
What are some examples of external abiotic factors?
Temperature, salinity, pH
What is a conformers internal environment depending on?
It’s internal environment is dependent upon its external
How do you conformers maintain optimum metabolic rates?
By using behavioural responses
How do you conformers his behavioural responses affect their metabolic rate?
The behavioural responses allow them to tolerate variation in the external environment to maintain optimum metabolic rate
What are the metabolic costs of a conformer?
low
Do conformers have a wide or narrow ecological niche?
A narrow ecological niche
Regulators can maintain their internal environment regardless of ________?
Regardless of the external environment
How do you regulators control their internal environment?
By using metabolism
Regulators using metabolism increases the range of what for the species?
Increases the range of possible ecological niche as they can survive in
What happens to the metabolic costs to achieve homoeostasis through regulation?
The metabolic cost increases
How does Thermoregulation occur by?
Through negative feedback
What is the temperature monitoring centre?
Hypothalamus
How is information communicated by the hypothalamus?
Electrical impulses through nerves to affecters, which bring about corrective responses to return temperature to normal
What are some corrective responses to an increase in body temperature?
Sweating, vasodilation, decrease metabolic rate
