The answer is A. Animals and crops, such as horses, were brought in to America. These new species competed with already existing species, like deer, for land, food, and water.
Explanation: The species are transported by man from his native region to the receiving locality. Most species die during this phase but still, there are many that overcome it. Transportation can be intentional, caused by a man for a specific purpose, such as food production, wood, soil improvement, gardening or hunting and fishing activities; or accidental, involuntarily and associated with communication routes, shipments of agricultural products, stowaways in freight transport, the discharge of ballast water in ports or the depletion of geographical barriers by engineering works.
