Answer:

Nuclear fusion

Explanation:

Nuclear fusion is a process whereby the nuclei of two smaller atoms combine to form a much larger atom, accompanied with the release of energy. This is opposed to nuclear fission where a larger atom splits into simpler and smaller atoms.

According to this question, the process of releasing energy when two stoms combine to form a larger atom is called NUCLEAR FUSION. A very common example of nuclear fusion is the combination of hydrogen atoms in the sun to produce Helium atom, with the release of heat energy.

With the aid of a food chain, describe how energy flows from the highest to the lowest..
Anika [276]

Answer:

Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level.

Explanation:

Energy is passed between organisms through the food chain. Food chains start with producers. They are eaten by primary consumers which are in turn eaten by secondary consumers. They are then eaten by tertiary consumers and in a long food day these can be eaten by quaternary consumers
