• Anthropogenic or artificial ecosystems are other names for man-made ecosystems. They are entirely the product of human activity. These ecosystems entail human input and do not evolve spontaneously on their own.
• Since agricultural crop fields are sustained by people to provide food, they are examples of artificial or man-made ecosystems.
• A region where plants, animals, and microbes interact with land, water and air to make a bubble of life is referred to as an ecosystem.
