Organisms And Populations Ques 2
2. The figure given below is a diagrammatic representation of response of organisms to abiotic factors. What do $\mathrm{a}, \mathrm{b}$ and $\mathrm{c}$ represent respectively?
[2010]
$ \begin{array}{|l|c|c|c|} \hline & \text { (i) } & \text { (ii) } & \text { (iii) } \\ \hline \text { (a) } & \text { conformer } & \text { regulator } & \begin{array}{c} \text { partial } \\ \text { regulator } \end{array} \\ \hline \text { (b) } & \text { regulator } & \begin{array}{c} \text { partial } \\ \text { regulator } \end{array} & \text { conformer } \\ \hline \end{array} $
$ \begin{array}{|l|c|c|c|} \hline \text { (c) } & \text { partial regulator } & \text { regulator } & \text { conformer } \\ \hline \text { (d) } & \text { regulator } & \text { conformer } & \begin{array}{c} \text { partial } \\ \text { regulator } \end{array} \\ \hline \end{array} $

Answer:
Correct Answer: 2.( d )
Solution:
- (d) In the graph, the line ‘a’ represents regulator, line ’ $\mathrm{b}$ ’ represents conformer and line ’ $c$ ’ represents partial regulator. Organism 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.
