No. Fever is an elevated body temperature set-point, often caused by infection. Metabolic heat is the normal heat produced from metabolism. A fever may increase metabolic rate and thus metabolic heat production.
Yes, all living cells produce some heat through respiration. Some plants, like the skunk cabbage, produce significant metabolic heat to melt snow or attract pollinators.
Not directly. You feel the result—your body temperature. When you exercise, you feel warmer because increased muscle activity generates more metabolic heat than your body can immediately dissipate.
BMR is the rate of energy expenditure at rest, measured in energy units (e.g., calories). Metabolic heat is one form of that energy output—the thermal energy produced. BMR includes all energy uses, while metabolic heat is specifically the heat byproduct.
