How are heterotrophs dependent upon autotrophs for survival?

Question 5 options:

Autotrophs release carbon dioxide required by heterotrophs for cellular respiration.

Autotrophs are able to produce the glucose heterotrophs require to produce ATP.

Autotrophs are able to supply heterotrophs with an unlimited supply of ATP molecules.

None of these

1 answer

The correct option is:

Autotrophs are able to produce the glucose heterotrophs require to produce ATP.

Heterotrophs depend on autotrophs because autotrophs can convert inorganic substances (like carbon dioxide and water) into organic compounds (like glucose) through processes such as photosynthesis. Heterotrophs then consume these organic compounds to obtain the energy (in the form of glucose) they need to produce ATP for survival.
