Final answer:
The prefix 'bio-' signifies life and is used in various biological terms to denote a connection to living organisms and their processes, such as biochemistry, biology, and biosphere.
Step-by-step explanation:
The prefix bio- means life, and it is foundational to various terms in biology, fully relating to the study and understanding of living organisms and their processes. For instance, biochemistry refers to the study of the chemical processes occurring in biological organisms, while biology itself is the study of living organisms and their interactions with one another and their environments. The biosphere encompasses all ecosystems on Earth, illustrating the profound extent to which life affects the planet. The prefix 'bio-' is also applied creatively beyond strict scientific terminology to convey ideas that center on life and living processes, such as 'biounderstanding' or 'biosensitive', as a way to emphasize the connection to life's processes.
