What is the biological definition for survival?

Click For Summary
SUMMARY

The biological definition of survival is fundamentally the state of living rather than dying, with no unique biological criteria established. The requirements for survival vary significantly among organisms; for instance, humans require a balanced oxygen level, while plants depend on carbon dioxide. The concept of survival can also be examined at different levels, including individual organisms, species, or even genes. A key term discussed is "Survival Value," which refers to the effectiveness of a characteristic in enhancing an organism's reproductive success.

PREREQUISITES
  • Understanding of basic biological concepts
  • Familiarity with ecological interactions
  • Knowledge of evolutionary biology principles
  • Awareness of organismal physiology
NEXT STEPS
  • Research the concept of "Survival Value" in evolutionary biology
  • Explore the differences in survival needs among various organisms
  • Investigate the impact of environmental factors on survival rates
  • Study the relationship between individual survival and species evolution
USEFUL FOR

Students of biology, ecologists, evolutionary biologists, and anyone interested in understanding the fundamental principles of life and survival in various organisms.

What is the biological definition for survival? What does an organism need to survive?

Survival is just living rather than dying. There's no special biological definition.

What is needed to live? It depends on the organism. Too much carbon dioxide will kill a human being, but plants need carbon dioxide.
 
I suppose you could distinguish between the survival of an individual vs. a species...or even for a single gene. My handy dandy biology dictionary has this to offer...

Survival Value - The nature or degree of the effectiveness of a given characteristic in promoting the organism's ability to contribute offspring to the future generation.
