A natural eco-system, as one example, would be the natural channel a river cuts through land, along with the trees and vegetation that grows along its banks and the animals and fish that live in or use the river or nearby land.
A man made eco system, as one example, is when men use machinery to cut a deeper or wider channel and create a lock and dam on part of the river, which often changes the amount of water or the quality of the habitat.
Some man made eco systems encourage vegetation and animal / fish, while other changes negatively affect habitat.
The difference between a human-made system and a "natural" system will depend entirely on what the system is. In many cases the human system will be simpler and have a narrow focus.
man-made structures were made by humans, but natural structures made itself.
A manmade system is created and designed by humans to serve a specific purpose or function, while a natural system exists in nature without human intervention and is governed by natural laws. Manmade systems can be modified or controlled by humans, whereas natural systems evolve and operate based on natural processes.
The solar system is natural.
Natural systems are not made by humans. The solar system is not made by humans, so it’s considered a natural system.

if you are a pro at diamond gazing then you will know the difference
Pooping.
A laser is man-made, a river is natural.
fistulas are natural occurring and shunts are man made devices
A manmade system is created and designed by humans to serve a specific purpose or function, while a natural system exists in nature without human intervention and is governed by natural laws. Manmade systems can be modified or controlled by humans, whereas natural systems evolve and operate based on natural processes.
The difference between organ system and tissue is that organs are made of many layers of tissue working together and a organ system is many organs working together as a system.
The difference between natural biological and man made methods is that the later uses chemical processes which can be harmful to the environment. Biological methods use evaporation, oxidation, and biodegradation to safely cleanup
canals are man made waterways, rivers are natural waterways
natural process is a process in whichit is naturally without any plan occured and the man made proceess is a process which is done by man.
