The correct Answer is:
To solve the question regarding the tree with spirally arranged deep constrictions on its trunk, we can follow these steps: ### Step 1: Understand the Characteristics of the Tree The tree exhibits spirally arranged deep constrictions on its trunk. This suggests that there is some external factor affecting the growth pattern of the tree. **Hint:** Look for factors that can cause physical changes in the structure of a tree. ### Step 2: Identify Possible Causes Consider various factors that could lead to deep constrictions on a tree trunk. Possible causes include: - Growth of climbing plants (lianas) - Parasitic plants - Environmental factors affecting oxygen supply - Specific growth patterns of certain species (like strangler figs) **Hint:** Think about how other plants interact with trees, especially those that grow on or around them. ### Step 3: Evaluate the Role of Lianas Lianas are woody climbers that can wrap around the trunks of host trees. As they grow, they can create constrictions due to their weight and the way they spiral around the trunk. This can lead to deep constrictions as the liana competes for space and resources. **Hint:** Consider the characteristics of lianas and how they interact with their host plants. ### Step 4: Consider Other Options - **Parasites:** While they can affect the host plant, they typically do not cause the same kind of structural constriction. - **Disturbed Oxygen Supply:** This would not specifically cause spirally constrictions. - **Strangler Nature:** This refers to specific plants like figs that can strangle their host but is not the primary cause for general constrictions. **Hint:** Eliminate options that do not directly relate to the physical structure of the tree trunk. ### Step 5: Conclude the Correct Answer Based on the analysis, the correct answer is that the deep constrictions on the trunk are due to the presence of lianas, which are woody climbers that spiral around the trunk and cause these constrictions. **Final Answer:** The deep constrictions on the trunk of the tree are due to the presence of lianas.
