The figure given below is a diagrammatic representation of response of organisms to abiotic factors. What do A, B and C represent respectively?
(a) A - conformer B - regulator C - partial regulator
(b) A -regulator B - partial regulator C - conformer
(c) A - partial regulator B - regulator C - conformer
(d) A - regulator B - conformer C - partial regulator
(d) A - regulator B - conformer C - partial regulator
Explanation:
In the graph, the line A represents regulator, line B represents conformer and line C represents partial regulator. Organisms that are able to maintain homeostasis by physiological means that ensures constant body temperature are called regulators. Organism that are not able to maintain a constant internal temperature are called conformers.
Partial regulators are organisms that have the ability to regulate, but only over a limited range of environmental conditions, beyond which they simply conform.
