A 50%

B 5%

C 20%

D 90%

Answer 1

hopefully it’s C. 20%

Answer 2

D. 90 %

Step-by-step explanation:

In an ecosystem, at each trophic level energy is lesser than the previous trophic level. Only 10% of energy is transferred to the next trophic level. 90% of energy is lost through metabolic processes as a heat when organisms from previous level are consumed by the organisms of next level.
