Ecosystem is a self-contained system or a biological community of living things (or biotic components) and their non-living (or abiotic components) environment which surrounds them.
Infact, we human beings are the only organisms in the ecosystem who can change/alter the environment for fulfilling our greeds, damaging its balance and health. The various threats to the balance of the ecosystem include deforestation, hunting & poaching, extinction of species & imbalance in food chain, rapid climatic changes etc. Neccessary steps must be taken in order to overcome such threats.
Hope this helps :)
