Basically, the P-P chain turns 4 protons into: 1 neutrino, 1 gamma ray, 1 positron, 1 helium nucleus.
A gamma ray = energy.
The chain converts hydrogen into helium and makes energy.
This is all occurring through fusion reactions where 2 protons basically smash into each other. But, it could also be e.g. a proton smashing with a deuterium nucleus. Or, other nuclei smashing together to make something else.
Hope this helps!

Answer:
speciation is when one species splits off into multiple species.
In-depth answer:
Speciation can happen in 4 different ways, the first being Allopatric Speciation, where 2 groups of the same species are physically separated for extended periods of time, and when they're re-introduced, they don't breed.
Sympatric Speciation is when 2 groups of the same species aren't seperated, but form different behaviors that isolate them reproductively (the groups wont inter-breed)
Parapatric Speciation is when 2 groups of the same species are suddenly placed into a new environmental niche, and adapt in different ways to fill that niche.
Quantum Speciation is much less recognized, but it's when a new species rapidly evolves and 'buds off' from the original group
