Question

based on the model of a food web in an ecosystem, which mathematical representation is most accurate for the flow of energy in this community? a 10% of the energy of the giraffe is available to the tree. b 10% of the energy of the grasshopper is available to the bird. c 50% of the energy of the rhinoceros is available to the lion. d 100% of the energy of the shrub is available to the deer.

Explanation:

The 10% energy transfer rule states that only ~10% of energy moves from one trophic level to the next. Option A is wrong because energy flows up, not down (tree → giraffe, not reverse). Option C uses 50% which violates the 10% rule. Option D claims 100% transfer, which is impossible (organisms use energy for metabolism). Option B aligns with the 10% rule for grasshopper (lower trophic level) to bird (higher level).

Answer:

B. 10% of the energy of the grasshopper is available to the bird.
