The correct Answer is:
To determine which of the given resources provide criteria for susceptibility to extinction, we need to analyze each option based on its impact on the likelihood of a species becoming extinct. ### Step-by-Step Solution: 1. **Understanding Susceptibility to Extinction**: - Susceptibility to extinction refers to the likelihood that a species will become extinct. Factors that increase this likelihood are usually related to reproductive rates, genetic diversity, and ecological roles. 2. **Evaluate Each Option**: - **(i) Large Body Size**: - Species with large body sizes often have lower reproductive rates. They tend to produce fewer offspring, which can lead to a higher risk of extinction if environmental changes occur. Therefore, large body size can be a criterion for susceptibility to extinction. - **(ii) Lower Trophic Level**: - Species at lower trophic levels (like herbivores) generally have higher population densities and are less susceptible to extinction compared to higher trophic level species. Thus, this option does not contribute to susceptibility to extinction. - **(iii) High Genetic Diversity**: - High genetic diversity within a population increases its resilience to environmental changes and diseases. This means that species with high genetic diversity are less likely to go extinct. Therefore, this option does not contribute to susceptibility to extinction. - **(iv) Low Reproductive Rate**: - Species with low reproductive rates produce fewer offspring, which can lead to population declines and increased risk of extinction. This option is a significant criterion for susceptibility to extinction. 3. **Conclusion**: - Based on the analysis, the options that provide criteria for susceptibility to extinction are: - (i) Large Body Size - (iv) Low Reproductive Rate ### Final Answer: The correct options that provide criteria for susceptibility to extinction are (i) Large Body Size and (iv) Low Reproductive Rate. ---
