Question

what does examining population ecology help us understand about our own human population? human population growth is unpredictable and we cannot be sure how to calculate it. our population growth hasnt been affected by ecological factors until the last 50 years. human population growth is uninfluenced by ecological factors so we live independently. human population growth can be understood using the same principles as other species.

Explanation:

1. Analyze the first option: Human population growth can be modeled (e.g., with exponential or logistic growth models), so it's not unpredictable and uncalculable. Eliminate this.
2. Analyze the second option: Ecological factors (like resource availability, disease, habitat) have always affected human population growth, not just the last 50 years. Eliminate this.
3. Analyze the third option: Human population growth is influenced by ecological factors (e.g., food supply, climate, disease), so we don't live independently of them. Eliminate this.
4. Analyze the fourth option: Population ecology studies population dynamics of species. Human population growth follows ecological principles (e.g., growth based on resources, competition, etc.) similar to other species. This is correct.

Answer:

D. Human population growth can be understood using the same principles as other species. (Note: Assuming the fourth option is labeled D; if the original labels were different, adjust the label but keep the text. Since the options are presented in order, the correct one is the last option: "Human population growth can be understood using the same principles as other species.")
