  4. Mutualism: • a symbiotic relationship in which both participating species benefit. • EX: Ant & Aphid - ant gets nutrition from the aphid’s honeydew— a sugary secretion from the aphid’s body. - the aphid gets protection from the ant against predatory insects like ladybugs.

  5. Commensalism • A symbiotic relationship in which one organism benefits and one is neither harmed nor helped. • Example: Epiphytes also known as “air plants.” live on the bark of trees. - The epiphyte gets space to live. - The tree is not harmed nor does it benefit in any way.

  6. Parasitism • Relationship in which one organism feeds on and usually lives on or in another. • Ex: tape worm. The tape worm lives inside the animals intestines and gets shelter and food. The animal loses nutrition, may lose weight and become ill.
