Question

Which information helps scientists determine the survival probability of a population?(1 point)

Answer 1

Scientists use a variety of information to determine the survival probability of a population, including:

1. **Birth and Death Rates:** Understanding the reproduction rates and mortality rates within the population helps estimate future population dynamics.
2. **Genetic Diversity:** A population with high genetic diversity may be more resilient to environmental changes and diseases, which can improve survival probabilities.
3. **Habitat Quality:** The availability and quality of resources such as food, water, and shelter significantly influence survival rates.
4. **Population Size:** Smaller populations may be more vulnerable to extinction due to factors like genetic drift and inbreeding depression.
5. **Age Structure:** The age distribution within a population can indicate potential growth or decline, as it reflects the proportion of individuals in reproductive versus non-reproductive stages.
6. **Environmental Factors:** Changes in climate, habitat destruction, and presence of predators or competitors can affect survival probabilities.
7. **Migration Patterns:** Understanding how movement to and from different populations influences genetic exchange and population stability.

Collectively, these factors can be used to model and predict the survival likelihood of a population over time.
