Solution

The correct option is A 1 only
Explanation:

Statement 1 is correct: Loss of energy is progressively higher for higher trophic levels because the species at higher trophic loss more energy due to metabolic heat and respiration.

Statement 2 is incorrect: Higher trophic levels tend to be less discrete because the organisms at progressively higher trophic levels receive energy from more than one source.
