Question

Identify the incorrect statement. 1. Speciation is generally a function of time. 2. Tropical environment is less seasonal, relatively more constant and predictable. 3. Solar energy contributes to high productivity 4. Temperate regions have remained relatively undisturbed formillions of years.

• A. 1, 2, 3, 4
• B. 44595
• C. Only 4
• D. 44624

Answer 1

The Correct Option is C

To identify the incorrect statement among the given options, let's analyze each one based on biological facts and reasoning:

1.  Speciation is generally a function of time.
   • \(Speciation\) refers to the formation of new and distinct species in the course of evolution. It is a process that occurs over time as genetic changes accumulate in a population. Thus, this statement is correct.
2. Tropical environment is less seasonal, relatively more constant and predictable.
   • Tropical regions near the equator tend to have a relatively constant climate, with less seasonal variation than temperate areas. This statement accurately characterizes tropical environments.
3. Solar energy contributes to high productivity.
   • Solar energy is a major factor in ecosystem productivity, particularly in photosynthesis, which is fundamental for plant growth. More sunlight usually means more productivity in regions, making this statement valid.
4. Temperate regions have remained relatively undisturbed for millions of years.
   • Temperate regions have experienced significant environmental and climatic changes over millions of years, such as ice ages. Therefore, this statement is incorrect because these areas have not remained undisturbed.

Based on the analysis above, the incorrect statement is option 4: "Temperate regions have remained relatively undisturbed for millions of years."
