Energy Transfer in Ecosystems

Please examine the provided food chain diagram from a real ecosystem: Grass → Grasshopper → Frog → Snake → Hawk

Explain the concept of a trophic level in the context of the food chain provided.

What percentage of energy is typically transferred from one trophic level to the next in an ecosystem?

In the given food chain, if the grass stores 10,000 units of energy, how much energy would you expect the grasshopper to receive?

Using the energy transfer percentage from question 2, calculate the approximate amount of energy the frog would receive from the grasshopper.

What happens to the majority of energy that is not transferred to the next trophic level? Give two examples of where this energy might go.

Discuss the implications of energy transfer efficiency for the population sizes of organisms at different trophic levels in the food chain.

How does the second law of thermodynamics apply to the energy transfer in the food chain?

Why is the energy content lower at the top of the food chain compared to the bottom?

Describe one way human activity can disrupt the energy flow in a food chain like the one provided.
