please could someone help me with these question please i have loked on websites but i am still stuck.
true or false and i need to write a comment why:-
plants photosynthesise 24 hours a day
respiration uses up carbon dioxide
false (photosynthesis requires light)
true (carbon dioxide is consumed and oxygen is produced)
First link I tried: photosynthesis does not occur at night.
If you are talking about respiration of humans, we exhale CO2 so we aren't using it up. Plants use CO2.
