Among two plots, plot ' H' is having less species compared to plot 'K' . Identify the statement that is correct for plot H and plot K.

Options

A. Plot 'X' shown less year to year variation in total biomass
B. Plot 'K' is. less resistant to natural disturbance
C. Plot 'H' has more productivity than plot 'K'
D. Plot 'K' has more productivity than plot 'H'

Answer

To solve the question regarding the characteristics of plot H and plot K, we need to analyze the information provided about the species diversity in both plots. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Concept of Species Diversity
- **Species Diversity** refers to the variety of species within a particular habitat or ecosystem. Higher species diversity typically indicates a more stable and productive ecosystem.

### Step 2: Compare the Species in Plot H and Plot K
- **Plot H** has fewer species compared to **Plot K**. This implies that Plot K has a higher biodiversity.

### Step 3: Relate Species Diversity to Productivity
- Generally, ecosystems with more species (like Plot K) tend to have higher productivity. This is because a greater variety of species can utilize resources more efficiently and contribute to overall biomass.

### Step 4: Analyze the Stability of the Ecosystems
- A stable community is characterized by minimal variation in productivity from year to year, resistance to disturbances, and resilience to recover from disturbances.
- Since Plot K has more species, it is likely to be more stable and resilient compared to Plot H.

### Step 5: Evaluate the Given Statements
1. **Statement 1**: "Plot H shows less year-to-year variation in total biomass."
- This is incorrect because fewer species typically lead to greater variability in productivity.

2. **Statement 2**: "Plot K is less resistant to natural disturbances."
- This is incorrect as more species usually confer greater resistance to disturbances.

3. **Statement 3**: "Plot H has more productivity than Plot K."
- This is incorrect because Plot H, with fewer species, is expected to have lower productivity.

4. **Statement 4**: "Plot K has more productivity than Plot H."
- This is correct because Plot K has more species, leading to higher productivity.

### Conclusion
The correct statement regarding the plots is that **Plot K has more productivity than Plot H** due to its higher species diversity.

### Final Answer
The correct statement is: **Plot K has more productivity than Plot H.**
