Based on the data provided, we can analyze the changes in the population of common groundsels over the time period in question:
1. **Population Size**:
- At the start, there were a total of \( 335 + 165 = 500 \) common groundsels.
- At the end, there were \( 3 + 597 = 600 \) common groundsels.
- The total population size actually increased from 500 to 600, indicating that the population has grown overall.
2. **Triazine Resistance**:
- At the start, 67% of the population had triazine resistance, while 33% did not.
- At the end, only 0.5% of the population had triazine resistance, compared to 99.5% without triazine resistance.
- This shows a significant decline in the percentage of plants with triazine resistance and a marked increase in the percentage of plants without triazine resistance.
Based on this analysis, we can conclude the following:
- The total population size did not decrease; it actually increased.
- The percentage of plants without triazine resistance did indeed increase significantly.
Thus, the correct understanding is:
- The total population size increased.
- The percentage of plants without triazine resistance increased.
So, the statements provided in the question are not accurate if considering population size—it increased, not decreased. However, it is true that the percentage of plants without triazine resistance increased.
