Question

Which of the following provides shelter for many living organisms?

• A. A-Horizon
• B. B-Horizon
• C. C-Horizon
• D. None of the above

Answer 1

The correct option is A A-Horizon

As we know, the soil is made up of many layers. These layers are called horizons. The topmost among these layers is A horizon. It is the layer parallel to the soil surface. It is rich in organic matter. It also contains humus, which is necessary for the proper growth of plants. Thus, we can say that A horizon has many necessary ingredients to support the plant and animal life.

So, option A 'A Horizon" is the correct answer.
