Question

question 2 points 2 which of the following statements about the 10% energy rule is true? (i) most incoming energy will be dissipated into the atmosphere as heat. (ii) energy is transferred from one trophic level to the next. (iii) cumulative loss of energy happens with each transfer in a food chain. statement i alone statements i and ii statement ii and iii statements i, ii, and iii

Explanation:

1. Analyze Statement I: In ecosystems, most energy (not just incoming, but at each trophic level) is dissipated as heat (e.g., through respiration), so this is true.
2. Analyze Statement II: The 10% energy rule is about energy transfer between trophic levels (e.g., from producers to primary consumers), so this is true.
3. Analyze Statement III: With each trophic level transfer, energy is lost (only ~10% moves to next level), leading to cumulative loss in a food chain, so this is true.

Answer:

Statements I, II, and III
