An example of homeostasis in living organisms is
A cooling effect resulting from evaporation of water from the body surface
B root hairs of a plant growing towards the source of light
C changing of the body colour of chameleon to match the colour of the foliage on which it is resting
D the release of phosphorus into the phloem of a plant growing in a phosphorus-deficient soil
Answer is D
Homeostasis is a living organism’s way of maintaining a stable internal environment even in the event of external environmental changes. When the plant keeps supplying phosphorus to the phloem even in the case of a deficiency in the soil, it maintains a steady balance on its inside irrespective of the lack in the soil.
