Moving up trophic levels, there is an increase in energy, entropy, and biomass.

True or False?

False. Energy is lost between levels due to things like respiration for heat and movement. In reality about 90% is lost between each trophic level, which is why us eating food from higher up is far less efficient than us eating a producer.

The statement that there is an increase in energy, entropy, and biomass when moving up trophic levels is false. Energy decreases at higher trophic levels due to loss during metabolic processes, and biomass typically decreases as well. Entropy increases as a result of energy transformations, confirming that higher trophic levels have lower energy and biomass.
