LIFE SCIENCE

Detailed explanation-1: -In the theory of natural selection, organisms produce more offspring than are able to survive in their environment. Those that are better physically equipped to survive, grow to maturity, and reproduce.

Detailed explanation-2: -Because resources are limited, more organisms are born than can survive: some individuals will be more successful at finding food, mating or avoiding predators and will have a better chance to thrive, reproduce, and pass on, their DNA. Small variations can influence whether or not an individual lives and reproduces.

Detailed explanation-3: -All organisms produce more offspring so that more can survive to adulthood and reproduce. This means that many of those offspring will die without reproducing. Only the survivors are able to reproduce pass their traits on to their offspring.

Detailed explanation-4: -Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Detailed explanation-5: -Species tend to produce more offspring than the environment can support. Individuals that are better adapted tend to survive and produce more offspring while the less well adapted tend to die or produce fewer offspring. Individuals that reproduce pass on characteristics to their offspring.
