I believe that the correct answer is D.)Animal Species
Animals reproduce , breed , and affect the agriculture.
Look up the word agriculture , you will see how my answer makes more sense.
My reason being is mainly because everything basically lives off of animals and if the are affected by anything and in any way start to decrease , the population will also.
I really hope that this helps you out a lot.
I believe the correct answer is D
Early humans moved from one location to another in order to hunt migrating herds.
I would say C because the king did repeatedly abuse our rights. Like the intolerable acts for instance shut down the port of massachusetts and hurt trade. Also the quartering act the sugar act the stamp act and a few more that evntually led us to civil war with him. We peacefully sent the king a olive tree branch petition which was supposed to be a sign of peace. But he rejected it and called us in full rebellion. So we fought for ourselves and won the civil war and made friends with britain as our main trade partner.
