Fission and fusion are nuclear reactions that produce energy, though they are not the same. Fission is the splitting of a heavy and unstable nucleus into two lighter nuclei. Fusion is the process where two light nuclei combine together releasing vast amounts of energy.
<span>Both of them are example of Passive transport and Passive processes; If that's the type of answer you are looking for.</span>

Carbon dioxide concentrations are expected to increase, because fossil fuel burning is expected to increase, because of an increase in agriculture and because more land will have to be cleared for increasing populations and agricultural use.
The classification is in this order: Kingdom, Phylum, Class, Order, Family, Genus Species.
The kingdom is the largest group, it contains the largest number of organisms who are the least related.
