Oxygen is used by both autotrophs and heterotrophs to release energy from glucose (as we know, the bonds between organic compounds can be used to release energy) in a process known as cellular respiration. Carbon dioxide, however, is predominantly used in autotrophs to perform photosynthesis because they cannot get their food any other way. The type of organism that is both an oxygen producer and carbon dioxide consumer is an autotroph. This is because they release oxygen during photosynthesis and require carbon dioxide to perform photosynthesis.

GMOs may lead to the use of different herbicides or pesticides is a true statement.
Explanation:
The GMO crops leads to growth of weeds that can resist herbicides other than for which the GMO is genetically-modified. The over-usage or over-reliance on herbicide-resistant GMO (Genetically modified organisms) crops had given way to the growth of such superweeds.
The main characteristic of these superweeds is resistance to the herbicides or the weedkillers leading to infestation of farmlands by these superweeds Hence farmers need to add different herbicides or pesticides to control the growth of superweeds.
