1. Food Chain: shows a linear progression of “who eats whom,” the flow of nutrients and energy through an ecosystem; arrows point from what is eaten to the eater (ex. carrot => bunny)

2. Food Web: similar to a food chain, but more complex; branches show all of the nutritional relationships for an entire ecosystem; can demonstrate the balance of an ecosystem

3. Symbiosis - interaction between two different organisms living in close physical association, typically to the advantage of both.

4. Mutualism is the way two organisms of different species exist in a relationship in which each individual benefits from the activity of the other. Similar interactions within a species are known as co-operation.

5. Commensalism - is a relationship between two organisms where one receives a benefit or benefits from the other and the other is not affected by it. In other words, one is benefited and the other is neither benefited nor harmed.

6. Carnivores: animals that eat only other animals.

7. Herbivores: animals that eat only plants.
