Plants are photoautotrophs. what does this mean? plants are photoautotrophs. what does this mean? they generate oxygen. they are the primary consumers of the biosphere. they are attracted to light. they synthesize their own food from inorganic materials. they use light energy to drive the synthesis of organic molecules from inorganic materials.

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.
