ecosystems are both strong and fragile

Ecosystems can be very strong as long as the diversity is large and the conditions remain in a nice balance. they are fragile when things are out of balance. I just thought of how we could compare an ecosystem like Yellowstone national park to that of the human body.In an ecosystem like Yellowstone, everything stays in balance if there is enough food, water, sunshine, space to live and hunt freely. Everything is in symbiotic coexistence as long as all these things are in order. Take away even one part of this balance and you can see the profound affects ie. if there was't enough rain, then the food would slowly be more and more sparce from the smallest insect all the way up to the bears. It is the same for the human body, if we don't get enough rest, water, food, sunshine we will begin to see over time how th imbalnce in one area affects the whole body ie. not enough sleep, can cause you to forget to drink enough water and maybe when your tired you're not as hungry, and we can go as far as to say that if we are tired we may stay home to nap instead of getting out on a nice sunny day. So let's be sure to be nice to every ecosystem we come into contact with from the biggest to the smallest, because they are all in delicate balance with each other.
