The figure below resulted from researchers dating old-growth forests in Pennsylvania. The thickness of the bars represents the number of new individuals added to the population at a given time. Select all that seem appropriate conclusions from this figure. American beech White pine Oaks (several species) Eastern hemlock 1550 1600 1650 1700 1750 Year established Oaks and White Pine tend to add individuals at the same time 1800 1850 1900 Eastern Hemlock and American beech were likely to be the most dominant species in the 1900s Eastern Hemlock and American Beech tend add individuals during the same time period White Pines seems to have added the most individuals between 1650 and 1725

Question
The figure below shows data from researchers studying old-growth forests in Pennsylvania. It illustrates the establishment of different tree species over time. ### Description of the Diagram: - **Graph Overview**: The horizontal axis represents the years from 1550 to 1900. The vertical axis lists four tree species: American beech, White pine, Oaks (several species), and Eastern hemlock. - **Bar Representation**: The thickness of each bar indicates the number of new individuals added to the population at a given time. ### Observations: 1. **American Beech**: Consistently added individuals from around 1550 to 1900, with variable thickness over the years. 2. **White Pine**: Shows a significant increase in individuals from around 1650 to 1750. 3. **Oaks**: Several pulses of new individuals, particularly from around 1600 to 1800. 4. **Eastern Hemlock**: Continual presence, with notable additions in the interval from 1700 to 1900. ### Conclusions Supported by the Figure: - **Oaks and White Pine**: Tend to add individuals around the same time periods. - **Eastern Hemlock and American Beech**: Likely to be the most dominant species in the 1900s. ### Additional Options: - The unchecked options suggest that Eastern Hemlock and American Beech don't consistently add individuals during the same time frame, and White Pines didn't add the most individuals between 1650 and 1725.
