 * This Population Dyanmics wiki is for you to discuss questions and share answers about symbiotic relationships.**
 * Need help understanding about symbiotic relationships? Then click on the above PowerPoint presentation.

Tell the relationship (**1. COMMENSALISM 2. PARASITISM 3. MUTUALISM) **between your animal pairs/add your name at the end of the relationship.

What is the relationship between an oxpecker and rhinoceros or zebra?** A symbiotic relationship is when two organisms of different species "work together," each benefiting from the relationship. One example of a symbiotic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra. Oxpeckers land on rhinos or zebras and eat ticks and other parasites that live on their skin. The oxpeckers get food and the beasts get pest control. Also, when there is danger, the oxpeckers fly upward and scream a warning, which helps the symbiont (a name for the other partner in a relationship). Tevin and Aidan

Barnacles create home sites by attaching themselves to whales. This neither harms nor benefits the whales. The relationship is mutalism. Taylor and Audrey Hermit crabs live in shells made and then abandoned by snails. This neither harms nor benefits the snails. Conner and Andrew

 * What is the relationship between buffaloes and cowbirds?**

As buffalos walk through grass, insects become active and are seen and eaten by cowbirds. This neither harms nor benefits the buffalos. Tanner and Chris

Mistletoe extracts water and nutrients from the spruce tree to the tree’s detriment.
 * What is the relationship between mistletoe and a spruce tree?**

Yucca flowers are pollinated by yucca moths. The moths lay their eggs in the flowers where the larvae hatch and eat some of the developing seeds. Both species benefit.
