Read the following statements and select the correct option:
(a) In an aquatic ecosystem, pyramid of biomass is inverted.
(b)Biomass depends upon reproductive potential and longevity of individuals.

Options

A. Both (a) and (b) are true
B. (b) is correct but (a) is false
C. (a) is correct but (b) is false
D. Both (a) and (b) are false

Answer

To solve the question, we need to evaluate the two statements provided and determine their correctness.

### Step 1: Analyze Statement A
- **Statement A**: "In an aquatic ecosystem, pyramid of biomass is inverted."
- In aquatic ecosystems, particularly in food chains involving phytoplankton, zooplankton, and fish, the biomass at the lower trophic levels (like phytoplankton) can be less than that at higher trophic levels (like fish).
- This results in an inverted pyramid of biomass, where the biomass of the consumers (fish) is greater than that of the producers (phytoplankton).
- **Conclusion**: Statement A is correct.

### Step 2: Analyze Statement B
- **Statement B**: "Biomass depends upon reproductive potential and longevity of individuals."
- Biomass refers to the total mass of living matter in a given area or volume, and it is primarily determined by the number of individuals and their size at a specific time.
- Reproductive potential refers to the ability of an organism to reproduce, and longevity refers to the lifespan of an organism. While these factors can influence population dynamics, they do not directly determine the biomass at any given moment.
- **Conclusion**: Statement B is incorrect.

### Step 3: Select the Correct Option
- Since Statement A is correct and Statement B is incorrect, the correct option is that Statement A is true and Statement B is false.

### Final Answer
- **Correct Option**: Statement A is correct, Statement B is incorrect.
