Artificial ecosystem are those ecosystem which are modified and managed by human beings.
Crop fields are man-made. Here plants do not grow naturally rather most of the plants are grown by humans according to the season, type of soil, etc. Crop fields are not like wild forest area, which is left to the care of nature and can sustain itself.
In crop fields, the land is managed, soil is prepared for sowing seeds, then irrigated and further progress is also kept under observation for getting good yield.
This is why, crop fields are known as artificial ecosystem.
