natural changes are changes that occur naturally and man has no part to play in these changes. Manmade changes are changes that occur due to man and man plays a role in these changes.

Natural disaster is a disaster caused by the effects of nature with no human activity. The Man made disasters would be like global warming where our global level temperatures due to increased fossil fuel burning in which we are responsible.
A man made change would be the building of a pond where there was not one naturally. The natural change would be a low lying field that floods and forms a pond.
A change in climate or natural disaster might change an ecosystem very quickly.
We don't spend a lot of time in natural ecosystems because where ever we are, chances are the biotic and abiotic factors has been changed. They change becuase humans changed it. When humans change the ecosystem it is no longer a natural ecosystem. We use natural ecosystems and turn it into thing's like golf courses, housing area's etc. So basically we are in non natural ecosystems most of the time. But the only time we do use (or are in) a natural ecosystem in when we are in/by a forest, pond (that was naturally made) etc. Hope that helped :)
anythng nd everythng can change the ecosystem
Ozone depletion causes UV to enter which destroy photoplanktons. They are useful for ecosystem.
Climate change can cause various effects. It causes living organisms to move from their natural habitat.

natural ecosystem must not be ineterfered by man, destruction of natural ecosystems leads to a change in the natural conditions of that ecosystem, whereas the agroecosystems are manipulated by man.
It's when nature changes the ecosystem. For example, CO2 is released by breathing, fires, trees dieing (being cut down), and thunder. Also, wild fires change the ecosystem by a tiny amount. The idea is that natural climate change is gradual, and so animals can evolve in time due to natural selection. Humans may have created global warming changes to the ecosystem too quickly for animals to evolve.

Tornadoes change habitats by destroying vegetation and manmade structures.
change through natural selection
One example of an Natural change is the overpopulation of wild animals which could change the ecosystem's food chain. Climate change could be a Natural change I recommend you to use more than 2 supporting documents when you mention about climate change. (eg graphs) As some people relate climate change as man-made.
