Dear student,
Artificial ecosystem is characterised by high productivity due to the human intervention. The weeds in the field are removed and the crops are taken care of for proper productivity by treating them with fertilizers. Water availability is regularly checked and provided with suitable amount of water. Parasites, rodents and birds are removed to maintain the proper equilibrium in the artificial ecosystem needed for high productivity.
