Explanation:

The law of conservation of energy states that energy is neither created nor destroyed, only changes form (B). In a closed - isolated system, total energy is conserved (D). Option A is about mass conservation, not energy. Option C is incorrect as not all energy is transferred in an energy pyramid; some is lost as heat.

Answer:

B. Energy is neither created or destroyed. it only changes form
D. In a closed system, i.e. a system that is isolated from its surroundings, the total energy of the system is conserved
