The correct answer is based on the widely recognized seven life processes that define living organisms. These processes are movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition. Integration, while important in the context of biological systems (especially in terms of how different systems work together), is not categorized as one of the seven fundamental life processes that all living organisms exhibit.

Respiration, reproduction, and growth are all essential functions of life. Respiration refers to the process of converting food into energy, reproduction involves producing offspring to ensure the continuation of species, and growth indicates an increase in size and mass as an organism develops. Each of these processes plays a critical role in the life cycle of an organism and is a fundamental characteristic of living beings.
