Đefine --- natural vegetation, wildlife and ecosystem?

Answer 1

Hi buddy,
........
...............
Natural vegetation means any plants or trees that grow on their own ‘naturally’ without any form of human intervention. 
Certain type of plants of trees have a natural place of origin or habitat, and before humans began to harvest vegetation and  cut down trees , this type of vegetation would grow naturally without any form of man-made chemicals such as pesticide, to manipulate its
growth.
Each  place on earth  had a community of plants that were natural and adapted to a specific area, and, more importantly, had grown accustomed to that climate zone. 
It is this type of plant community that is referred to as "natural vegetation”. 

wildlife------Wild animals collectively; the native fauna (and sometimes flora) of a region
living things and especially mammals, birds, and fishes that are neither human nor domesticated
Wildlife traditionally refers to undomesticated animal species, but has come to include all plants, fungi, and other organisms that grow or live wild in an area without being introduced by humans.

Ecosystem-----An ecosystem is a community of living organisms (plants, animals and microbes) in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.

Hope it helps u....
