Question 1
Which one of the following is an artificial ecosystem?

(a) Pond
(b) Crop field
(c) Lake
(d) Forest

Answer 1

Option (b) is correct.
An artificial ecosystem meets all the criteria of a natural ecosystem but is made and controlled by humans. It is created to mimic a natural ecosystem but often is less complex and with a very low genetic diversity. Orchards, farmlands, a garden and man-made reservoirs are some examples of artificial ecosystems.
