Need help asap please :( I think its C but I don't think that's right Which of the following most correctly represents biomanipulation through the top-down model?

Addition of quaternary consumers, so that tertiary consumers can decrease
Removal of tertiary consumers, so that secondary consumers can increase
Addition of primary producers, so that secondary consumers can increase
Removal of secondary consumers, so that tertiary consumers can increase

I am taking this flvs test right now and I think it might be A or B

I think the final answer would be A

Explanation:

The reason I don't think its C because the addition of primary producers wouldn't directly affect secondary consumers. It would first affect the primary consumers.

The only answer that would directly affect a certain group is A.

the offspring would all be white. if the parents are both white flowers then they have the genotype rr, which when crossed results in an all white punnet square.
