Question

read the passage below to build your understanding of the topic:
natural selection is a process where organisms that are better adapted to their environment tend to survive and reproduce more than others. this leads to evolution, which is the gradual change in species over time. adaptation is a characteristic that helps an organism survive in its environment. competition occurs when organisms fight for the same resources, like food or space. fitness is the ability of an organism to survive and reproduce in its environment. sometimes, humans choose which organisms will reproduce, a process called artificial selection.

4. The passage mentions: "Sometimes, humans choose which organisms will reproduce, a process called artificial selection." So the answer is Artificial selection.
5. The passage defines: "Fitness is the ability of an organism to survive and reproduce in its environment." So the answer is fitness.

Answer:

1. natural selection
2. Competition
3. adaptation
4. Artificial selection
5. fitness
