Relative to roots, the shoots are massive in plants of

Options

A. Deserts
B. Moist temperate
C. Tundra
D. Moist tropical forests

Explanation

To solve the question "Relative to roots, the shoots are massive in plants of," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Ecosystem Context**:
- The question asks about the relationship between roots and shoots in plants, specifically in different ecosystems.

2. **Identify the Ecosystems Mentioned**:
- The ecosystems mentioned are deserts, moist temperate regions, tundra, and tropical areas.

3. **Analyze Each Ecosystem**:
- **Deserts**: Plants in deserts often have extensive root systems to access deep water sources, but their shoots are typically not massive due to water scarcity.
- **Moist Temperate Regions**: These areas have a balanced environment, but plants may not have massive shoots relative to roots.
- **Tundra**: The tundra has a short growing season and harsh conditions, leading to smaller plants with less developed shoots.
- **Tropical Areas**: Tropical rainforests have high temperatures and high rainfall, which supports large and diverse plant life. Here, shoots can be massive due to the favorable growing conditions.

4. **Conclusion**:
- Based on the analysis, plants in tropical areas (specifically tropical rainforests) have massive shoots relative to their roots due to the abundant resources available for growth.

5. **Final Answer**:
- The correct answer is **tropical areas**.
