Based on the model, what do you conclude about the energy flow in ecosystems?
Understand the Problem
The question is asking about the conclusions that can be drawn regarding energy flow in ecosystems based on a model. It presents multiple choice options related to how energy behaves throughout the food chain and trophic levels.
Answer
Energy decreases as it moves from one trophic level to the next.
Energy decreases as it moves from one trophic level to the next.
Answer for screen readers
Energy decreases as it moves from one trophic level to the next.
More Information
Energy flow in ecosystems is unidirectional and involves passing energy from the sun to producers, then to consumers, with significant energy loss at each trophic level. Commonly, only about 10% of the energy is transferred to the next level.
Tips
A common mistake is assuming energy is perfectly conserved through trophic levels, when in fact much is lost as heat.
