2.4 - Metabolism in conformers and regulators Flashcards
What are the abiotic factors that affect metabolic rate?
Temperature, salinity and pH
What behavioural responses by conformers allow?
They allow them to tolerate variation in their external environment to maintain optimum rate
What is a Conformer?
A species which’s internal environment is dependent upon external environment
What is a Regulator?
A species where their internal environment is maintained regardless of their external environment
How do Conformers maintain their metabolic rate?
Using behavioural responses
How do regulators control their metabolic rate?
Metabolism
What type of species has a wider range of ecological special?
Regulator
What is the Hypothalamus?
Temperature monitoring centre
What are responsive ways to correct an increase in body temperature?
-Sweating
-Vasodilation (of blood vessels)
-Decreased metabolic rate
What is Sweating?
Body heat used to evaporate water in the sweat, cooling the skin
What is Vasodilation?
Increased blood flow to the skin increases heat loss
