Question

what are manmade ecosystem and natural​

Answer 1

Answer:

A natural ecosystem occurs in nature. Examples are pristine forests, the sea floor,  and rivers. Natural  ecosystems are self-regulatory. They can survive even without human interventions. Natural ecosystems are very rich in  biodiversity and natural resources.

Man-made ecosystems, on the other hand, are created to copy the conditions of natural ecosystem. Examples of man-made ecosystems are orchards, home aquarium, zoo, botanical gardens and park. These ecosystems are sustained by human interventions.
