Which explanation best fits with the data shown? a. the efficiency with which chemical energy is transferred from one trophic level to the next does not follow a predictable pattern. b. the efficiency with which chemical energy is transferred from one trophic level to the next increases from the bottom of the pyramid to the top. c. the efficiency with which chemical energy is transferred from one trophic level to the next decreases from the bottom of the pyramid to the top. d. the efficiency with which chemical energy is transferred from one trophic level to the next is about the same for all trophic levels.

i believe it is c.

because the amount of energy a consumer receives is decreased by 90% every trophic level.

for example, a herbivore would receive 10% of the energy that a plant would have stored.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
