An inverted pyramid of ……... May be observed in …..... Communities .

Options

A. Energy, grassland
B. Energy , forest
C. Biomass , marine
D. Biomass , forest

Answer

To solve the question "An inverted pyramid of ……... May be observed in …..... Communities," we need to analyze the options provided and understand the concept of inverted pyramids in ecological communities.

### Step-by-Step Solution:

1. **Understanding Inverted Pyramids**:
- In ecology, an inverted pyramid typically refers to a situation where the biomass or number of individuals decreases as you move up the trophic levels. This is contrary to the usual pyramid shape where biomass or number increases at lower trophic levels.

2. **Identifying the Types of Pyramids**:
- There are three main types of ecological pyramids:
- Pyramid of numbers
- Pyramid of biomass
- Pyramid of energy
- It is important to note that the pyramid of energy cannot be inverted; it always has a broad base and narrows at the top.

3. **Evaluating the Options**:
- **Option 1: Energy in Grassland**:
- This is incorrect because the pyramid of energy cannot be inverted.
- **Option 2: Energy in Marine**:
- This is also incorrect for the same reason as above.
- **Option 3: Biomass in Marine**:
- This is correct. In marine ecosystems, particularly with phytoplankton as primary producers and zooplankton as primary consumers, the biomass of zooplankton can be greater than that of phytoplankton due to the rapid reproduction and short lifespan of phytoplankton.
- **Option 4: Biomass in Forest**:
- This is incorrect because while there can be an inverted pyramid of numbers (e.g., in the case of parasites and herbivores), it is not typically an inverted pyramid of biomass.

4. **Conclusion**:
- The correct answer is "An inverted pyramid of biomass may be observed in marine communities."

### Final Answer:
An inverted pyramid of **biomass** may be observed in **marine** communities.
