3) Assertion: Both elements and compounds are called pure substances. Reason: They are made of same kinds of atoms or molecules. ... Reason: They are chemically mixed with each other.

4)Compounds have different properties from the elements that make them. ... The atoms of different elements are held together in compounds by chemical bonds. Chemical bonds can hold atoms together in large networks or in small groups. Bonds help determine the properties of a compound.

a) Plants, animals, and microbes are interdependent. This makes the ecosystem self-regulating and self-sustaining with all the components of the ecosystem. So, the correct answer is option A. Both assertion and reason are true and reason is the correct explanation of assertion.
