Question

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

Explanation:

Organic compounds are characterized by carbon - atom bonding with other atoms. Inorganic compounds lack this specific carbon - bonding feature. Photosynthesis is just one process to form some organic compounds, not a defining difference. Organic compounds can come from living and non - living sources. Inorganic compounds don't have a strict rule of containing oxygen and hydrogen atoms.

Answer:

Organic compounds contain carbon atoms bonded to other atoms.
