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 fill in the blanks with the correct terms based on our understanding of ecological pyramids.

### Step-by-Step Solution:

1. **Understanding the Concept of Ecological Pyramids:**
- Ecological pyramids represent the distribution of biomass, numbers, or energy among trophic levels in an ecosystem.
- Typically, these pyramids are upright, meaning that the biomass or number of organisms decreases as we move up the trophic levels (from producers to herbivores to carnivores).

2. **Identifying the Inverted Pyramid:**
- An inverted pyramid occurs when the biomass at a higher trophic level is greater than that at the lower level.
- This is commonly observed in aquatic ecosystems, particularly in marine environments where the biomass of higher trophic levels (like fish) can exceed that of the primary producers (like phytoplankton).

3. **Filling in the Blanks:**
- The first blank should refer to the type of pyramid, which is "biomass."
- The second blank should refer to the type of community where this phenomenon occurs, which is "marine."

4. **Final Answer:**
- Therefore, the complete sentence is: "An inverted pyramid of biomass may be observed in marine communities."
