Identify the following symbiotic relationships by writing down M, C, or P in each space below in the picture. M = Mutualism C = Commensalism P = Parasitism

*Some orchids grow on trees. That way the orchids get more sunlight and protection. === Commensalism *The oxpecker lands on a zebra and eats the bugs and parasites that live on the zebra's skin. === Mutualism *The egret will eat insects that have been disturbed as the cattle search for food. === Commensalism *Ticks harm their hosts by biting their skin and sucking their blood and causing them to itch. === Parasitism *The plover flies into the mouth of a crocodile and feeds on the decaying meat. The crocodile gets its teeth clean and the plover eats a meal. === Mutualism *The remora attaches itself to a shark. When the shark feeds, the remora detaches itself and eats the extra food. === Mutualism *A spider makes a web on the tree. === Mutualism *There are many kinds of bacteria that live in our intention. These bacteria help us digest food and they get food. === Mutualism *An aphid is a small insect that feeds on the sap of plants. === Parasitism
