Question

question 5 points 2 which of the following statements is/are true? (i) the pyramid of energy explains the relationship between energy and trophic level. (ii) the pyramid of energy deals with number of calories gained per trophic level. (iii) the pyramid of energy begins with producers and ends with the higher trophic levels. statements i and ii statements ii and iii statements i only statements i, ii, and iii

Explanation:

• Statement I: The pyramid of energy shows the energy flow (in kcal or joules) at each trophic level, so it explains the energy - trophic level relationship. This is true.
• Statement II: Energy in an ecosystem is often measured in calories (or kilocalories). The pyramid of energy represents the amount of energy (calories) available at each trophic level, so it deals with calories gained per trophic level. This is true.
• Statement III: In a food chain, the pyramid of energy starts with producers (who capture solar energy) and then proceeds to higher trophic levels (herbivores, carnivores, etc.) as energy is transferred. This is true.

Answer:

Statements I, II, and III
