Ecosystems are both strong and fragile

Within an ecosystem everything is closely connected in an integrated system. An ecosystem can be both strong and fragile at the same time; everything is interdependent; one element feeds another element which keeps the system strong and balanced;

The intricate interconnection can also make an ecosystem fragile; if you take one element for example; phosphate out of the earth by mining, the whole system then has a lack of phosphate; so trees aren't being nourished and plants might not grow well in the area, because the earth is depleted.

If you reduce the water flow; the whole water quality can be affected, if you decrease certain plants; you could change the food source or habitat for creatures large and small.
