The figure given below is a diagrammatic representation of response of organisms to abiotic factors. What do $(i)$, $(ii)$ and $(iii)$ represent respectively ?
$(i)$-conformer,$(ii)$-regulator,$(iii)$-partial regulator
$(i)$-regulator,$(ii)$-partial regulator,$(iii)$-conformer
$(i)$-partial regulator,$(ii)$-regulator,$(iii)$-conformer regulator
$(i)$-regulator,$(ii)$-conforme,$(iii)$-rpartial regulator
Solution
(d) : Some organisms are able to maintain homeostasis by physiological (sometimes behavioural also) means which ensures constant body temperature, constant osmotic concentration, etc. They are known as regulators. A majority of animals and plants cannot maintain a constant internal environment. Their body temperature changes with the ambient temperature. These animals and plants are simply conformers. During the course of evolution, the costs and benefits of maintaining a constant internal environment are taken into consideration. Some species have evolved the ability to regulate, but only over a limited range of environmental conditions, beyond which they simply conform. They are known as partial regulators.
