Competition for the needs of life is defined as what?

• A. Gene Pool
• B. Descent with Modification
• C. Struggle for Survival
• D. Artificial Selection

Answer: (C)

Competition for the needs of life is about the struggle for survival. Resources like food, water, shelter, and mates are limited, so individuals must contend with each other to obtain what they need. Those with traits that help them compete more effectively or endure environmental pressures are more likely to survive and produce offspring. Over generations, this differential survival and reproduction shift the population’s traits through natural selection. The other ideas describe related but different concepts: the gene pool is the total genetic material in a population, descent with modification explains how evolution changes traits over time, and artificial selection is human-directed breeding rather than a natural competition.
