Which is not true regarding biodiversity?

Options

A. It provides more productive ecosystem
B. It changes along the altitude
C. Highest in tropical regions
D. Increases with the increase in latitude

Answer

To determine which statement regarding biodiversity is not true, let's analyze each option step by step.

### Step 1: Analyze the first statement
**Statement 1:** "It provides more productive ecosystem."
- Biodiversity is known to enhance ecosystem productivity. More species can lead to more efficient resource use and greater stability. Therefore, this statement is **true**.

### Step 2: Analyze the second statement
**Statement 2:** "It changes along with the altitude."
- Biodiversity does indeed change with altitude. Different altitudes have varying climates, which can support different types of organisms. Thus, this statement is also **true**.

### Step 3: Analyze the third statement
**Statement 3:** "Highest in tropical region."
- Tropical regions are known for their high biodiversity due to favorable climate conditions, such as warmth and moisture. This statement is **true**.

### Step 4: Analyze the fourth statement
**Statement 4:** "Increases with the increase in latitude."
- This statement is **not true**. Generally, biodiversity tends to decrease as one moves away from the equator (increasing latitude). Colder climates and harsher conditions at higher latitudes support fewer species. Therefore, this statement is false.

### Conclusion
The statement that is not true regarding biodiversity is option **4**: "Increases with the increase in latitude."
