The question in this segment consists of two statements, one labelled as "Assertion A" and the other labelled as "Reason R". You are to examine these two statements carefully and decide if the Assertion A and Reason R are individually true and if so, whether the reason is a correct explanation of the assertion. Select your answers to these items given below. Assertion (A): Decay and decomposition of dead organic matter (leaves and dead animal bodies) by microbes is a chemical reaction. Reason (R): In a chemical change original substance and its properties are changed to new material with new properties.

The correct option is the Assertion A and Reason R are individually true and the reason is a correct explanation of the assertion.
- Decaying is a process in which waste like leaves, dead animal bodies, and other organic matter is broken down. As a result, simpler forms are obtained and ultimately, nutrients are obtained.
- This decaying process is facilitated by some bacteria or fungi.
- Thus, complex waste products are changed into simple nutrients.
- The properties of the reactants and products are different. Hence, it is an example of chemical change.
- As we can see, both assertion and reason are correct and the reason is the correct explanation of assertion.
