Affiliate Marketing Secrets

I have to right this paragraph in biology about how if an endangered species became extinct, then how would it affect the rest of the organisms. I also need to use the words niche, population, and community in the paragraph. My endangered animal is a plant, so wouldn’t everything decline? I still don’t know how I’m going to fit niche in there. Any help will be appreciated considering that this due tomorrow, thanks.
