Question

Part 3:
Explain how the ecosystem that you selected follows the law of conservation of mass and the law of conservation of energy. It is said that only about 10% of stored energy is transferred between trophic levels of the ecosystem. Be specific in using your ecosystem in your example

Answer 1

Well the Law of conservation of mass states that mass is neither created nor destroyed in any ordinary chemical reaction. The Law of conservation of energy states that energy cannot be created or destroyed it can only change from one form into another or transferred from one object to another.
I don't know what you ecosystem is so I can't comment on the rest.
