Solution Summary

Symbiosis is a close association between two different types of organisms in a community having beneficial or deleterious consequences for at least one of the parties. Mutualism is a relationship in which members of two different species benefit and neither suffers. Commensalism is a relationship in which 'one party gains some benefit, whilst the other suffers no serious disadvantage. Parasitism is a relationship in which one member of the association benefits while the other is harmed

3. Complete the following describing these types of symbiosis.

Mutualistic Relationship Organisms Involved Interaction of organisms involved
Root Nodules

Rhizobia (bacteria) & Leguminous Plants Plant provide space and nutrition to Rhizobia which in turn fixes the atmospheric nitrogen for plants.
Lichen

Algae & Fungi Algae being photosynthetic provide food to fungi and fungi provides space to algae
Trichonympha/Pyrsonympha

Termite/Trichonympha and Pyrsonympha
The Trichonympha and Pyrsonympha digest wood for the termite
Ants and Acacia

Ants/acacias
Ants feed from acacia nectaries and eat beltian bodies/nodules. Ants protect the acadia from herbivores and girdle branches to let more light in to the acacia.

4. Complete the table describing these types of commensalism.

Mutualistic Relationships Organisms Involved Interaction of the organisms involved
Epiphytes

Epiphytes - Various mosses, ferns, bromeliads, and orchids/Other plants.
Epiphytes grow on other plants obtaining nutrients from rainwater and decaying leaves -not from the host
Remora

Remora/Fish (sharks) and turtles
Attaches to sides of other fish and turtles and eats food they drop.
Clown fish

Clown fish/ Sea anemone The clown fish lives among the deadly tentacles of a sea anemone and eats food left by the sea anemone.

Barnacles/whales and manatees, ships and other things in the ocean. Barnacles attach as harmless hitchhikers. Some species of barnacles are found only as commensals on the jaws of whales. And there are other species of barnacles found only as commensals on those barnacles. Barnacles on top of barnacles!
