Each member of a food chain is unique to sustain an ecosystem. When one part is thrown off, the entire ecosystem is affected because of the interdependency of an ecosystem. The sun provides energy for the plants. Producers include all green plants and harness their energy from the sun. Consumers are every organism that eats something else. There are four types of consumers: herbivores, carnivores, parasites, and scavengers. Linking the chain together are the decomposers. Decomposers are mainly bacteria and fungi that convert dead matter into gases to be released into the air. Decomposers recycle the nutrient to again be used by the producers.

The beak and talons of eagles are specific to birds of prey. The eyes of eagles are the sight organ, and the tongue is the taste organ. Eagles are very opportunistic animals and will generally eat whatever is available to them at that time. While bald eagles prefer the taste of fish they also eat small animals such as rabbits or lizards; and also fruits as well. The eagle’s eyes suit it to its environment so that it is able to view its prey from a distance and swoop in for the kill. The eyes of a bald eagle are four times the strength of humans, allowing it to be at top of food chain. Since the eagle is at the top of the food chain, it is more susceptible to harmful toxins. Eagles are not generally eaten by anything unless they are already dead- then they are subject to prey for the coyotes or cougars- otherwise the only other harmful affect would be the human hunters.
An eagle uses the warm air updrafts generated by chosen terrain in order to soar. An eagle would not be suited to other environments due to these factors. The key adaptations that a bald eagle has are the ability to see much further and clearer than humans. When it comes to seeing objects at a distance, their eyes are...
