Question

how is an organic compound different from an inorganic compound?
organic compounds contain carbon atoms bonded to other atoms
inorganic compounds contain oxygen atoms and hydrogen atoms
organic compounds come only from nonliving things.
photosynthesis is responsible for organic compounds

Explanation:

Organic compounds are defined as compounds that contain carbon atoms bonded to other atoms (such as hydrogen, oxygen, nitrogen, etc.). Inorganic compounds can vary widely, but the key differentiator for organic compounds is the presence of carbon - based bonding.

• The second option is incorrect because many organic compounds also contain oxygen and hydrogen atoms.
• The third option is wrong as organic compounds can come from living things (e.g., glucose from plants).
• The fourth option is too narrow as not all organic compounds are from photosynthesis (e.g., methane from anaerobic bacteria).

Answer:

Organic compounds contain carbon atoms bonded to other atoms.
