Answer

Brief Explanations:

  • All organisms must compete for resources like food, space, etc., for survival, so the first statement is true.
  • Mutations are random and not a direct response to survival - struggle for reproduction. So the second statement is false.
  • Organisms with favorable phenotypes have a competitive advantage in their environment, making the third statement true.
  • All living organisms, including plants, undergo natural - selection, so the fourth statement is false.
  • Natural selection is an ongoing process in nature, so the fifth statement is true.
  • Successful phenotypes are more likely to be passed on, becoming more prevalent over generations, so the sixth statement is true.
  • A decrease in food availability usually leads to more intense competition and may reduce variation as less - fit individuals are selected against, so the seventh statement is false.

Answer:

  • All organisms must compete for survival.
  • Some organisms have phenotypes that make them better competitors than others in their environment.
  • Natural selection continues to occur even today.
  • Phenotypes found in the most successful members of a species become the most prevalent after several generations.
