What would have a bigger impact on a grassland ecosystem,
removing all coyotes or all rabbits? explain.

both

Explanation: if the Coyotes are gone then the rabits over populate but if the rabits are gone then the coyotes starve to death because they have no food.

Removing all rabbits.

Explanation:Because the other carnivores out there (including people who eat rabbit meat) will not be able to have rabbits as an option of food for survival.

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.
