Conservation of Energy Essay
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 your explanation of how this does not contradict the law of conservation of energy. Be sure t

Answer 1

Hi what would you like help with on this? Also it chopped off your question.

Answer 2

I believe you posted this question somewhere else and so I'll just paste what I've written from before, and hopefully it'll give you some insight on how to start your essay. Though you, yourself, will need to research it further to expand on certain points.

Answer 3

I believe that the laws of CONSERVATION of mass and the CONSERVATION of energy states that the mass and energy will stay the same (assuming that it is indeed within a "closed" system). When speaking in terms of the ecosystem, this is what we would consider an "open" system where, animals can increase or decrease populations by eating it's prey or giving birth to its own kind. The law of conservation of energy still applies however, think of it this way. When a bird is eating an insect, per say, energy can neither be created nor destroyed, but can be converted from one form to another,such as heat from flying/ catching prey/ used for bodily functions. The body needs a constant supply of energy in order to support life. Though you might think the energy used is now "gone", IT ISN'T, it has just simply tranformed into a different kind of energy. Whereas when talking about the energy pyramid, they say that only 10% of energy is transfered to the next organism. What happened to the other 90%? Remember, we said that most of the energy CANNOT be destroyed, only transformed into another type of energy, that is why.


This also proves how it does not contradict the law of conservation of energy while you might need to expand on the trophic levels bit (talk more about the energy pyramids)
