Affiliate Marketing Secrets

My fiance is getting a 870 remington shotgun for my valentines day present. I’m okay with it but I don’t know anything about it. I’ve recently been exposed to firearms though him and his family (they’re military/police affiliated) and feel like the noob..
I want to know everything about this shotgun. What does it feel like? (I’ve shot a mosin nagant with out the recoil pad is it like that? that hurt..) What is good about it being a home defense weapon? What are it’s flaws? How accurate is it? What kind of shells does it take? What shells are best for it? Etc.. What are good sites to look up such information?

the choices are:
a.different species can share the same niche in the same habitat
b.no two species can share the same niche in the same habitat
c.two species in the same habitat have to share a niche to survive
d.different species can occupy niches that are very similar
which sentences are true???
