Which describes the role of decomposers in the carbon cycle?

a.
they prevent carbon from escaping into the atmosphere.

b.
they absorb carbon from carbon dioxide in the atmosphere.

c.
they change carbon dioxide into a form that organisms can use.

d.
they release the carbon that remains in the bodies of dead organisms.

answer: c

explanation:

the energy generated by an individual's metabolism is calculated in met (metabolic equivalent of task). the met is the ratio of the work metabolic rate to the resting metabolic rate. one met is illustrated as 1 kcal per kilogram per hour, and is probably equal to the energy cost of sitting quietly.

1 met is equal to 1.162 watt per kg

1 kg is equal to 1000 grams

as the person weighs 80000 gm, that is, 80 kg.

therefore, 80*1.162 = 92.96

thus, the person expends 92.96 watts of power while at rest.
