Which of the following statement is incorrect ?

Options

A. Speciation is generally a function time.
B. Tropical environment unlike temperate ones are less seasonal .
C. Constant environment does not promote niche specialization.
D. There is more solar energy available in tropics

Answer

To solve the question "Which of the following statement is incorrect?", we will analyze each statement provided in the options one by one.

### Step 1: Analyze the first statement
**Statement 1:** "Speciation is generally a function of time."
- **Analysis:** This statement is correct. Speciation, the process by which new species arise, typically requires a significant amount of time for populations to diverge genetically and evolve into distinct species.

**Hint:** Think about how long it takes for significant evolutionary changes to occur in populations.

### Step 2: Analyze the second statement
**Statement 2:** "Tropical environments, unlike temperate ones, are less seasonal."
- **Analysis:** This statement is also correct. Tropical environments tend to have a more stable climate with less variation in temperature and precipitation throughout the year compared to temperate regions, which experience distinct seasons.

**Hint:** Consider how climate patterns differ between tropical and temperate regions.

### Step 3: Analyze the third statement
**Statement 3:** "Constant environment does not promote niche specialization."
- **Analysis:** This statement is incorrect. A constant environment can actually promote niche specialization because species can adapt to specific roles within a stable environment, leading to greater species diversity. Therefore, this statement contradicts ecological principles.

**Hint:** Reflect on how species adapt to their environments and the role of stability in promoting diversity.

### Step 4: Analyze the fourth statement
**Statement 4:** "There is more solar energy available in the tropics."
- **Analysis:** This statement is correct. The tropics receive more direct sunlight throughout the year, leading to higher solar energy availability compared to higher latitudes.

**Hint:** Think about the angle of sunlight and how it affects energy distribution on Earth.

### Conclusion
After analyzing all statements, we find that **the incorrect statement is the third one**: "Constant environment does not promote niche specialization."

### Final Answer
The incorrect statement is: **Option 3** - "Constant environment does not promote niche specialization."
