How does genetic diversity affect biodiversity in an area provide an example

When humans farm large plantation of one cash crop, they reduce the biodiversity of the region because they reduce the genetic diversity of the species in the environment. A reduction in genetic diversity means that the genetic variability of the species is reduced  hence there are fewer sub-species in the environment. This ultimately reduces the biodiversity of the ecosystem -  which is the variability among all the living organisms in the environment.

answer; i believe the correct answer is (sporophyte);

for 8 am not sure maybe yes?

for 9 if it is asking if the male is more or less it would be less

hope i even just a little : )
