Symbiosis

1. Symbiosis In this activity you will examine a series of photographs. Each photo shows a different type of symbiotic relationship (mutualism, commensalism or parasitism). Look at each photograph and determine which type of symbiotic relationship it illustrates and what organism benefits (+), is harmed (-), or neither harmed nor helped (0)by the relationship.

2. Symbiosis Bumble bee picks up pollen and transfers it to other plants for pollination. Plants need to be pollinated in order to reproduce. Bees gather nectar from the flower for food for the other bees in their hive.

7. Symbiosis Barnacles attach but don’t harm the whale. The barnacles use their feathering appendages to sweep the surrounding water for small, free floating organisms.

8. Symbiosis Lichens are a sandwich of fungi and algae. Fungus forms a protective envelope for the algae and the algae uses nutrients absorbed by the fungus. The sugar and oxygen produced by the algae are used for food by the fungus.

9. Symbiosis The Viceroy butterfly is protected from vertebrate predation by mimicking the Monarch butterfly.

10. Symbiosis Tapeworm in human. Tapeworms diminishes the nutrients from the human.

11. Symbiosis The coral sweeps for organic material from the water, metabolizes it and forms carbon dioxide and nitrogenous wastes. The dinoflagellates, which live in the coral use the wastes in photosynthesis to form oxygen and sugars that the coral uses to survive.
