Kilogram

The kilogram was first based up on an object located in france which was a kilogram, and from that every scale and balances were calibrated, the problem was that it was decaying like every element on earth with time, that was created in 1889, and ever since it has been loosing weight because of this decay, it has los 50 micrograms, which is equivalent to a 2 cm hair or an eyelash, now is changing to be correlated to the planck constant, which never changes her or in the universe, this is very important because the SI is meant to be universal, for all the people throughout the time.

If the plant absorbs 50 kcals of energy units, how much energy will the mushroom get from hawk that ate mouse that ate plants.
irakobra [83]
The mushroom will get 0.05 kcals of energy units in the end. This is because at each level, you only pass on 10% of the energy, which then results in the mushroom getting only 0.05 kcals by the end.
