According the First Law of Thermodynamics, Energy Is Conserved

Multiple Choice

According the first law of thermodynamics, energy is conserved. That is, the internal energy of a system changes as energy flows in or out of it. In biological terms, this can be interpreted as meaning that whenever energy is transformed from one form to another, some is lost (typically as thermal energy) . What does this tell us in relation to the structure of an ecological pyramid?

A) Whenever an organism eats another, not all of the energy consumed is converted into usable energy.
B) There will always be fewer top predators than those that are consumed at the base.
C) The number of mid-range organisms in a pyramid will be fewer than those at the top.
D) All of the options listed are correct.
E) The number of mid-range organisms in a pyramid will be more than those at the bottom.
