An Ecosystem
We have a pond with a thriving ecosystem including grasses, pond lilies, ducks, fish, beavers, and turtles. There is an oil spill in this small Bastrop pond. How can this affect the organisms in the ecosystem?
The grass is dying and no longer a good food source. The beavers, ducks, and turtles travel to a new pond to try to survive.
The fish die. The pond lilies die.
