Let me you precise and short answer:
According to the best estimates, volcanoes release about 130-230 million tonnes (145-255 million tons) of CO2 into the atmosphere each year. Emissions of CO2 by human activities amount to about 27 billion tonnes per year (30 billion tons).

Carbon dioxide exhaled with each day:
Humans exhale about 1 kg of carbon dioxide per day. The exact amount depends on age, sex, size, and most importantly activity level. Multiply that by a world population of six billion and you get a very large number.
However, human exhalation of carbon dioxide is part of a closed system. Th...

This is a difficult question to answer in terms of carbondixide because it will vary widely,depending on the amount of exertion a person undergoes in a day, and what they eat.
(For methane it's easy-people don't exhale methane).
The estimated average daily calorie intake is 1940 calories per day for women and 2550 for men. Since you haven't specified which sex, let's take the average of 2245.
