The right answer is to measure the amount of released carbon dioxide.
The carbon dioxide exhaled by the lungs can reflect the energy consumed by the body since it comes from the degradation of glucose which is the main energy substrate. And this is a better indicator of energy consumption than measuring heart rate because it can be inflected by several factors.
A is false because glucose is not found in the urine, except in the case of diabetes mellitus.
C is false because the consumption of calories does not mean that we will directly use it.
D is wrong because perspiration is independent of energy consumption, this is a way to cool the body after exercise.

Explanation:
The pyramid of biomass is a diagram that exhibits the total biomass of the organisms at different trophic levels, which are required to support life in a given ecosystem. This pyramid usually starts with producers situated on the bottom (e.g., plants), then continues with the organisms that eat these primary consumers (herbivores), after with secondary consumers (carnivores), and so successively. The pyramid of biomass indicates the amount of mass of 1-primary producers required to support the life of the primary consumers, 2- primary consumers needed to support the life of the secondary consumers, 3-secondary consumers needed to support the life of the tertiary consumers, and so successively for each trophic level. In this diagram, the trophic level with a higher amount of biomass (and energy) is usually represented by the producers (i.e., by organisms on the bottom), and this amount of biomass decreases as long as more levels are considered. In consequence, if more food from secondary consumers is consumed, it will produce an increase in the percentage of biomass that is needed to support life.

not nucleus, only nucleoid
