Answer and explanation:
It is said that an ecosystem is balanced when there is a functional system that helps the prompt recovery of wildlife after some natural event of disastrous characteristics.
This means that it is necessary to have flora and fauna in good condition, with a food chain of predators and preys, that toxic gases have decreased or disappeared, among other issues. We will find a balanced ecosystem when the relationship between natural organisms and human beings is pleasant and harmonic enough and does not imply a risk to nature and its conservation.
