How It Works

Symbiosis is the interaction between organisms in an ecosystem. These interactions can be helpful, harmful, or have no effect. There are many different types of symbiosis, such as competition, predation, parasitism, mutualism, and commensalism. One example on the cards are ants and acacia trees. Ants burrow into the acacia tree to eat sugars. The ants also give the tree protection from other animals. Since the tree gets protection and the ant gets food, both benefit, which makes the relationship an example of mutualism.
