An inverted pyramid of biomass can be found in which ecosystem?

Options

A. Forest
B. Marine
C. Grassland
D. Tundra

Explanation

**Step-by-Step Solution:**

1. **Understanding the Concept of Biomass Pyramids:**
- A biomass pyramid represents the total mass of living matter at each trophic level in an ecosystem. It can be upright or inverted.
- An upright pyramid indicates that biomass decreases as you move up the trophic levels, while an inverted pyramid indicates that biomass increases as you move up.

2. **Identifying the Types of Ecosystems:**
- The question provides four options: forest, marine, grassland, and tundra.
- Each of these ecosystems has a different structure in terms of biomass distribution.

3. **Defining Inverted Pyramid of Biomass:**
- An inverted pyramid of biomass occurs when the primary producers (like phytoplankton in marine ecosystems) have less biomass than the higher trophic levels (like fish).
- This is contrary to most terrestrial ecosystems where plants (producers) have the highest biomass.

4. **Analyzing the Marine Ecosystem:**
- In marine ecosystems, the primary producers (phytoplankton) are small and have low biomass. However, they support a large biomass of consumers (like fish).
- This leads to an inverted pyramid shape, where the biomass of consumers is greater than that of producers.

5. **Conclusion:**
- Based on the analysis, the ecosystem that exhibits an inverted pyramid of biomass is the marine ecosystem.

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