Question

Which of the following is NOT a segment of the environment?

• A. Lithosphere
• B. Hydrosphere
• C. Atmosphere
• D. Biosensor

Hint:

Logic Tip: The prefix tells the story: "Atmo" = air, "Hydro" = water, "Litho" = stone. They all end in "sphere" (meaning a globe/domain). A "sensor" is a little electronic gadget, clearly not part of the Earth's structural anatomy.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
The natural environment is traditionally divided into four main interconnected segments that support life on Earth.
Step 2: Key Formula or Approach:
The four segments are:
Atmosphere: The gaseous envelope surrounding the Earth.
Hydrosphere: All water bodies (oceans, rivers, lakes, ice).
Lithosphere: The outer solid shell of the Earth (crust and upper mantle).
Biosphere: The zone where life exists.

Step 3: Detailed Explanation:
A biosensor is an analytical device used for the detection of a chemical substance, combining a biological component with a physicochemical detector. It is a man-made tool, not a natural segment of the Earth's environment.
Step 4: Final Answer:
Biosensor is not a segment of the environment.
