  1. LIVING RELATIONSHIPS SYMBIOSIS

  2. Other Nutritional Relationships: • SYMBIOSIS- • Any close relationship between two organisms of different species

  3. COMMENSALISM • Benefits one organism; the other organism neither benefits nor is harmed • This is an example of the cattle egret and a rhinoceros • The cattle egret feeds off the insects stirred up when the rhino moves. • The text mentions the red-breasted goose and the peregrine falcon

  4. PARASITISM • Benefits one organism; the other (host) is harmed • This example is a braconid wasp which lays its eggs on a tomato hornworm caterpillar. • The wasp lays its eggs on the hornworm. When they hatch, they digest the hornworm from the inside. • Other examples are fleas, ticks, tapeworms, nematodes

  5. MUTUALISM • Both organisms benefit • Here, there are ants that live in the acacia tree. • The acacia tree produces nectar “gifts” for the ants. In return, the ants protect the tree from any plant-eating insects. • Another example is the tunneling shrimp and the goby fish.

  6. Symbiotic Relationships
