How does eating contribute to the flow of energy in a ecosystem

Eating contributes to the flow of an ecosystem because in a food web/chain, there is always a consumer. Starting from the very bottom of the food web/chain, all organisms eat to pass on the energy to the next cosumer. For example, a grasshopper eats some grass. That grass is made into energy. Then, a possum eats that grasshopper, the energy from the grasshopper converting to the energy of the possum. Then a giant snake comes along and eats the possum. The energy keeps flowing up and up the food chain as animals consume(and be consumed).

answer; /// i do believe that the correct answer is (a) boiling

- aluminum and copper chloride.

- the chloride ion to separate the aluminum from the oxygen so that the aluminum can react with the copper ions (and the water molecules).
