Metals are the most abundant
Answer:
Because it is the product of two more basic units, mass and acceleration. The calculation of force is as follows:
Force=mass*acceleration
Mass is a base unit, acceleration is a derived unit calculated as a function of length and time which are both base units.
Any unit definition that is a function of more basic units is considered a derived unit.
The law of conservation of energy states that energy cannot be created nor destroyed, but it transforms from one form to another.
this also applies in a food chain, for energy is decreased by 90% when moving down to the next animal (or trophic level), but it is not created nor destroyed, for the first source of energy in a food chain is always the sun, and the sun is an infinite source of energy
