Question

pyramid below to answer the question. energy pyramid for an aquatic ecosystem. the energy pyramid shows some of the organisms that live in the same aquatic ecosystem. how does the energy at level 5 compare to the energy available to the organisms at level 3? there would be 10 times less energy available to level 5 than to level 3. there would be 100 times less energy available to level 5 than to level 3. there would be 10 times more energy available to level 5 than to level 3. there would be 100 times more energy available to level 5 than to level 3.

Explanation:

In an energy pyramid, energy transfer between trophic levels follows the 10 - 20% rule. As we move up the pyramid from one level to the next higher level, about 90% of the energy is lost. So, moving from Level 3 to Level 5 (2 levels up), the energy available at Level 5 is 10% of 10% (or 1%) of the energy at Level 3. That means there is 100 times less energy available at Level 5 compared to Level 3.

Answer:

There would be 100 times less energy available to Level 5 than to Level 3.
