Mill Pond Ecosystem

A pond ecosystem is a peaceful one; beside the constant killing of organisms by the ecosystem's consumers. Consumers need to feed off of other organisms in the ecosystem to survive. Without food, the ecosystem cannot function properly because the organisms will die on their own. Higher level consumers rely on the animals below them in the food chain to survive, as do the lower level consumers to the producers. Every organism needs some form of energy to live.

The hydra is one of the lowest organisms on the food chain in the pond ecosystem. Do not be fooled though; It itself is a first level consumer. Hydras eat amoeba, worms, and other microscopic organisms.

Every organism in an ecosystem relies on each other. Even taking out just one of the many organisms, it could lead the entire ecosystem's doom. For example, if all the hydras in this mill pond ecosystem were to disappear, the fathead minnows would have nothing to eat, causing them to die off. Without fathead minnows, painted turtles would have nothing to eat, causing them to die off, and so on until the entire ecosystem no longer has any organisms.

The fathead minnow plays a significant role in this ecosystem. It is eaten by the bald eagle, raccoon, and painted turtle. Without the fathead minnow, the above organisms would have one less organism to feed off of. Without food, the organisms have no way of surviving. The raccoon, for example, eats both the painted turtle and the fathead minnow. If the fathead minnow were to go extinct from the ecosystem for some reason, the painted turtles might go extinct as well due to the lack of food. If the painted turtles and fathead minnows are gone, that leaves less food for the raccoon, which can possibly wipe them out of the ecosystem as well. Think of this as a "chain reaction" effect.

In this video, you will see how a bald eagle captures its prey. To snatch a fish, they use their incredible vision to spot a fish, swoop down and catch it in its beak.

In this video, you will see how a raccoon catches its prey. It does so by swimming around in the water and spotting something it thinks looks like a nice snack. Raccoons are not very picky with their choice of food; they will eat just about any animal in its ecosystem.
