what happens to the amount of energy available as you move up trophic levels? increases decreases

Brief Explanations:

In an ecosystem, energy transfer between trophic levels (like from producers to primary consumers, then to secondary consumers, etc.) is inefficient. Typically, only about 10% of the energy from one trophic level is passed on to the next. As we move up trophic levels (e.g., from herbivores to carnivores), the amount of available energy decreases because energy is lost at each level through processes like respiration, heat loss, and undigested matter.

Answer:

B. decreases
