What are the essential survival needs for organisms?

The correct answer identifies the fundamental survival requirements for organisms: food, oxygen, water, body temperature, and atmospheric pressure.

Food is essential as it provides the nutrients and energy necessary for growth, maintenance, and reproduction. Organisms rely on oxygen for cellular respiration, which is vital for converting food into usable energy. Water is crucial for all biochemical reactions, maintaining hydration, and regulating body temperature.

Body temperature is significant because many biochemical processes are temperature-dependent. Most organisms have a specific temperature range in which they can survive and function optimally. Atmospheric pressure influences various physiological functions, including gas exchange in aquatic and terrestrial environments.

This comprehensive understanding of essential survival needs emphasizes the interplay between these factors in sustaining life. Other choices do not encompass the complete set of critical needs identified in the correct answer, as they either omit some of the key components or include elements that are less fundamental to survival.
