Which of the following statements is true regarding how energy moves up the food chain?
A
All of the energy is not transferred from producer to consumer because some of the energy is destroyed.
B
All of the energy is transfer from producer to consumer.
C
All of the energy is not transferred from producer to consume because some of the energy is lost as heat.
D
None of the above.
Verified step by step guidance1
Understand the concept of energy transfer in a food chain: Energy flows from producers (like plants) to consumers (like herbivores and carnivores) in an ecosystem.
Recognize that energy transfer is not 100% efficient: Only a portion of the energy is transferred from one trophic level to the next.
Identify the reason for energy loss: Energy is lost primarily as heat due to metabolic processes, as described by the second law of thermodynamics.
Evaluate the given statements: Compare each statement with the concept of energy transfer and energy loss in ecosystems.
Determine the correct statement: The statement that aligns with the concept of energy loss as heat during energy transfer is the correct one.
