Which of the following is NOT one of the seven functions of life?

The correct choice indicates that communication is not one of the seven functions of life. The seven functions of life are generally recognized as nutrition, homeostasis, reproduction, growth, response to stimuli, excretion, and metabolism.

Nutrition refers to the intake and processing of nutrients to provide energy and materials for growth and repair. Homeostasis involves maintaining a stable internal environment despite external changes, which is crucial for the survival of organisms. Reproduction is the biological process whereby new individual organisms are produced, ensuring the continuation of a species.

While communication is certainly important in the context of social organisms, particularly in complex systems like human societies or animal groups, it does not fit into the biological requirements for life as defined by the fundamental characteristics essential for survival and reproduction. Therefore, it is correctly identified as not being one of the seven functions of life.
