Fission and fusion are different nuclear reactions.
It isn't, in general. Thermonuclear bombs use a fission bomb to generate the heat and pressure required to start the fusion process, but there are other ways of doing it (stars do so by gravity, for instance).
Nuclear bombs can use either nuclear fission or nuclear fusion as the primary mechanism of energy release. Most nuclear bombs in current arsenals rely on nuclear fission reactions, while thermonuclear bombs use a fission reaction to trigger a fusion reaction.
a hydrogen bomb is a fusion bomb. even though in standard types of hydrogen bombs 90% of the yield is fission, caused by uranium-238 fission by 15 MeV neutrons from the fusion reaction.
Detonation of a fusion hydrogen bomb is initiated by the primary fission bomb, which generates high temperatures and pressures needed to trigger fusion reactions in the hydrogen isotopes. The fission bomb compresses and heats the fusion fuel to the point where nuclear fusion reactions can occur, releasing vastly more energy than the fission reaction alone.
Fat Man was a fission bomb, meaning that it relied on the splitting (fission) of heavy nuclei like uranium-235 to release energy.

Fission and fusion
explain how a fusion reactor would be similar to a fission reaction
Not fusion, but a fission reaction.
fission and/or fusion
Fusion or fission.
fusion nuclear reaction followed by fission nuclear reaction
Fission is the opposite reaction to fusion. Fission involves the splitting of a heavy atomic nucleus into lighter elements, releasing a large amount of energy in the process.
To some degree. Hydrogen bombs release energy via nuclear fusion, but they use a fission reaction to trigger the fusion.
Nuclear energy is either:fission reaction, orfusion reaction, orradioactive decay
It isn't, in general. Thermonuclear bombs use a fission bomb to generate the heat and pressure required to start the fusion process, but there are other ways of doing it (stars do so by gravity, for instance).
