Explanation / Answer

7. Biological respiration,is a natural source of carbon dioxide emission and around the same quantity gets removed naturally.

So it should be in a safe range , but human sources or activities of emissions have upset its natural balance.

87 percent of all human produced carbon dioxide emissions come from burning of fossil fuels.

So the answer is NO, that is biological respiration have less effect than burning of fossil fuels.

8.The carbon dioxide released when burning wood is about 1900 gram carbon dioxide for each 1000 gram of wood burnt.

Burning wood can be considered carbon neutral because it does not increase the amount of co2 cycling through the atmosphere that is the co2 which was taken by the tree from air when it grew itself is released when wood is burnt.
