What is a sustainable ecosystem?

Answer: A sustainable ecosystem can be defined as a type of environment (biological environment) in which there are numerous types of species living in their habitats and everyone present there is able to survive and live together without any external support or help from the outside of their habitat. 

• When we say that there is a sustainable ecosystem we mean that there is every element present which will be needed by the species living there so that they do not have to be dependent on the outside world for their survival.
