Answer:
<em>The correct option is 1000 units of energy.</em>
Explanation:
Most of the energy at each trophic level gets lost in the form of heat. Only a little amount of energy passes from one trophic level to the other. Scientists conclude that only about 10% of energy passes from one trophic level to another.
Hence, the flowers having 100,000 units of energy will pass 10,000 units of energy to the butterflies. The butterflies will pass 1000 units of energy to the birds.
The answer would be A, Gold.
Once the the amount of gold posited in the earth's crust or mantle is used up or depletes then there is no way to to replenish the gold deposition. This is not the case of the others because you can use reforestation to replenish a forest, water cycle replenishes the river as well as the carbon cycle shows how carbon can be replenished (NOTE: coal is carbon but carbon is not necessarily coal so where as carbon can easily be replenished, it is not the same for coal which is non-renewable).
This solution will work, because the amount of rocks and the size of the rocks also depend on how much farther you will move, although once you start to build up a little bit of inertia it will become easier.
Hope this helps!
