Answer
Brief Explanations:
- In nature, resources are limited, so all organisms must compete for survival, which makes the first statement true.
- Mutations are random and not a direct response to struggling for survival, 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 in a species tend to become more prevalent over generations through natural selection, so the sixth statement is true.
- A decrease in food availability usually leads to more intense competition and may reduce variation in a population 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.
