Maximum biomass occurs in temperate forests.

Answer

**Step-by-Step Solution:**

1. **Understanding the Statement**: The statement claims that maximum biomass occurs in temperate forests. We need to analyze this claim.

2. **Definition of Biomass**: Biomass refers to the total mass of living matter in a given area or volume. It is often associated with the productivity of an ecosystem.

3. **Comparison of Forest Types**:
- **Tropical Rainforests**: These forests are known for their high levels of biodiversity and productivity. They receive abundant rainfall (200 to 350 cm per year) and have warm temperatures year-round, which supports a wide variety of plant and animal species.
- **Temperate Forests**: In contrast, temperate forests experience moderate rainfall and have distinct seasons. They do not support as much biodiversity or productivity as tropical rainforests.

4. **Conclusion**: Given the conditions of tropical rainforests, they have the highest biomass due to their warm temperatures, high rainfall, and rich nutrient availability. Therefore, the statement that maximum biomass occurs in temperate forests is false.

5. **Examples of Tropical Rainforests**: Notable examples include the Amazon Basin in South America and the Congo Basin in Africa, both of which are characterized by their vast biodiversity and high productivity.

6. **Final Statement**: The maximum biomass occurs in tropical rainforests, not in temperate forests, making the original statement incorrect.
