The living system maintains chemical and physical conditions through homeostasis, where organisms adjust their internal environment and temperature to achieve equilibrium. Thus, option B is correct.
What is homeostasis?
Homeostasis is the organism's ability to maintain the equilibrium by optimal conditions and functioning that balances the internal chemical factors. Shivering and sweating are examples of homeostasis.
The internal environment is conserved and protected from external changes like sugar, nutrition, temperature, fluid availability, injuries, etc.
Therefore, in homeostasis, equilibrium is balanced by adjusting the internal environment.
