Question

The figure given below is a diagrammatic representation of the response of organisms to abiotic factors. What do a, b and c represent respectively?

• A. Conformer - Regulator - Partial regulator
• B. Regulator - Partial regulator - conformer
• C. Partial regulator - regulator - conformer
• D. Regulator - Conformer - Partial Regulator

Answer 1

The correct option is D Regulator - Conformer - Partial Regulator

For an organism to perform its physiological functions at maximal efficiency, the organism should try to maintain constancy of its internal environment despite varying external environments. This process of maintaining a constant internal environment in an organism is termed as homeostasis and is achieved by using various strategies.
- Regulator: These Organisms maintain homeostasis by physiological means which ensures constant body temperature, constant osmotic concentration, etc. Therefore, in the given figure,(B) represents this behavior.
- Conformer: A majority of organisms cannot maintain a constant internal environment. Such organisms change their body temperature with the ambient temperature. Therefore, in the given figure,(A) represents this behavior.
Therefore, A represents the regulator, B represents the conformer and C represents a partial regulator response of an organism to the abiotic factors.
