Solution:
An artificial ecosystem is the one that is created and maintained by human beings. Agriculture or crop field is the largest man-made ecosystem and a type of terrestrial ecosystem. Such ecosystems have almost no value except for exhibition and studying a bit of ecology, e.g. aquarium.
The artificial ecosystem is characterised by a lack of self-regulatory mechanisms, but the presence of simple food chains, little diversity, and high productivity.
