Answer:
8. B
9. B
10. C
Step-by-step explanation:
8. Species diversity can be seen as the different animals in an ecosystem, such as a cat compared to a fish. They have many different kinds of factors that make them unique! Genetic diversity though talks primairly about genes, meiosis is the main cause of genetic diversity to the swip-swap of the mother and father sex cells.
9. Biodiversity is what makes a specific species unique! Without biodiversity, everybody and everything would be the same! Everyone would have the same hair, eyes, height, if it's a feature on someone or something, it'd be the same.
10. Crop rotation only primairly effects humans and not so much the ecosystem, considering all the adverse effects the rest of the options have.
