If the cups were labeled as 'grass,' 'rabbit,' 'snake,' and 'eagle,' what does the change in water level between these cups demonstrate?
Understand the Problem
The question is about understanding a concept related to energy transfer in an ecological model. It is asking what the changes in water level across labeled cups represent in terms of energy transference in a food chain.
Answer
The loss of energy at each trophic level.
The change in water level between these cups demonstrates the loss of energy at each trophic level.
Answer for screen readers
The change in water level between these cups demonstrates the loss of energy at each trophic level.
More Information
Energy transfer in a food chain is typically inefficient, with significant energy loss as heat during respiration at each level.
Tips
A common mistake is assuming energy increases or remains the same throughout the food chain.
