Question

question 1
which statement is true about the energy and trophic levels within a food web?
each trophic level receives about 24% of the energy of the preceding level.
there is no limit to the number of trophic levels in an ecosystem.
it is more effective to eat organisms at lower trophic levels.
the energy transfer between trophic levels is a highly efficient process.

Explanation:

In a food - web, energy transfer between trophic levels follows the 10 - 20% rule, meaning only about 10 - 20% of energy is passed on to the next level. Higher trophic levels have less available energy. Eating organisms at lower trophic levels is more energy - efficient as more of the original energy is still available. There is a limit to the number of trophic levels due to energy loss.

Answer:

It is more effective to eat organisms at lower trophic levels.
