To solve the question regarding the effects of loss of biodiversity, we will analyze each statement provided and determine whether it is true or false based on our understanding of biodiversity and its implications.
### Step-by-Step Solution:
1. **Understanding Loss of Biodiversity**:
- Loss of biodiversity refers to the extinction or elimination of species from the earth. This can be caused by various factors, primarily human activities such as deforestation, habitat fragmentation, pollution, and climate change.
2. **Analyzing Statement 1**: "Gene pool of a species."
- The gene pool is the total collection of genes in a population. When biodiversity is lost, particularly through extinction, the gene pool is reduced because there are fewer individuals contributing genes to the population.
- **Conclusion**: This statement is **True**.
3. **Analyzing Statement 2**: "Number of interactions in the biota."
- Biodiversity contributes to numerous interactions among species (e.g., predator-prey relationships, symbiosis). If species are lost, these interactions diminish, leading to a less complex ecosystem.
- **Conclusion**: This statement is **True**.
4. **Analyzing Statement 3**: "Ability of species to adapt themselves to changes in the environment."
- A diverse gene pool allows for greater variation, which is crucial for adaptation to environmental changes. Loss of biodiversity reduces this variation, hindering the ability of species to adapt.
- **Conclusion**: This statement is **True**.
5. **Analyzing Statement 4**: "Non-evolutionary advancements."
- Non-evolutionary advancements refer to traits or characteristics that do not arise from evolutionary processes. The loss of biodiversity does not directly affect these advancements because they are not dependent on the genetic diversity of a population.
- **Conclusion**: This statement is **False**.
6. **Analyzing Statement 5**: "The surviving and newly evolving species to dangers of extinction."
- The extinction of certain species does not inherently put newly evolving species at risk. New species may adapt and thrive despite the loss of others, as they may possess the necessary genetic traits for survival.
- **Conclusion**: This statement is **False**.
### Final Conclusion:
- Based on the analysis, the true statements are 1, 2, and 3, while statements 4 and 5 are false. Therefore, the correct answer to the question is that the loss of biodiversity reduces the gene pool, the number of interactions in the biota, and the ability of species to adapt to environmental changes.
### Summary of True/False Statements:
