An inverted pyramid of biomass can be found in which ecosystem

Options

A. Forest
B. Marine
C. Grass land
D. Tundra

Answer

To determine in which ecosystem an inverted pyramid of biomass can be found, we need to understand the concept of the pyramid of biomass and how it varies across different ecosystems.

### Step-by-Step Solution:

1. **Understanding the Pyramid of Biomass**:
- The pyramid of biomass is a graphical representation that shows the total biomass at each trophic level in an ecosystem. It typically has producers at the base and consumers at the top.

2. **Identifying Trophic Levels**:
- In a typical pyramid of biomass, the biomass decreases as you move up from producers (first trophic level) to primary consumers (second), secondary consumers (third), and so on. This is known as an upright pyramid.

3. **Inverted Pyramid of Biomass**:
- An inverted pyramid of biomass occurs when the biomass of producers is less than that of the consumers. This is unusual and typically seen in specific ecosystems.

4. **Examples of Ecosystems**:
- In terrestrial ecosystems like forests, grasslands, and tundras, the pyramid of biomass is usually upright because producers (plants) have a higher biomass than the herbivores and carnivores that consume them.
- In contrast, in aquatic ecosystems, particularly marine environments, the situation can be different. Here, phytoplankton (the primary producers) have a lower biomass compared to the larger biomass of zooplankton and fish (the consumers).

5. **Conclusion**:
- Therefore, the ecosystem where an inverted pyramid of biomass can be found is the **marine ecosystem**.

### Final Answer:
An inverted pyramid of biomass can be found in the **marine ecosystem**.
