Day 1 - producer/consumer, predator/prey, and parasite/host relationships

  1. Review cells

  2. Tennessee Science Workbook page 40 (producer/consumer)

  3. Tennessee Science Workbook page 58-59 (predator/prey)

  4. For Graphic Organizer book create a 6 door shutter organizer. On the door write producer/consumer, predator/prey, and parasite/host. Inside each door write the definition of the word. When the doors are opened an illustration to show the meaning of the relationship.

Day 2 - predation, mutualism, commensalism, or parasitism

  1. Tennessee Science Workbook page 56

  2. Discuss each relationship with PowerPoint

    • commensalism - relationship between two living organisms where one benefits and the other is neither harmed nor helped

      • using a second organism for housing such as small mammal or bird that lives in holes in trees or orchids which live in trees

      • birds that live among cattle to eat the insects stirred up as they walk - egrets hunt for insects near a grazing animal's mouth

      • clownfish lives among the forest of tentacles of an anemone and is protected from potential predators

      • one animal attaching itself to another for transportation such as barnacles attach to shells or whales or a shrimp riding on a sea slugs

      • A remora is a small fish that attaches itself to the underside of a shark. There it feed upon leftovers from shark’s meals.

    • parasitism - one organism, usually physically smaller of the two (the parasite) benefits and the other (the host) is harmed

      • insects such as mosquitoes feeding on a host

      • tapeworm or hookworms living in host's gut

      • ticks and fleas that live in a host animal's fur - bite the animals and drink its blood

      • spider mites suck sugar from plants

      • The roots of the Owl Clover are partly parasitic on the roots of other desert wildflowers.

      • Milkfish eats algae

      • Venus flytrap and the pitcher plant eats insects with their leaves

    • mutualism - both species benefit from the interaction
      PowerPoint with examples of mutualism http://facstaff.bloomu.edu/ccorbin/mutualismexamples.ppt

      • flowers and their pollinators (examples:  bees and hummingbirds gather nectar and spread pollen)

      • birds and mammals eat berries and fruits while plant benefits by the dispersal of it seeds

      • coral reefs- the corals get food and the algae get protection

      • algae and fungi > lichen - alga gets water and nutrients from the fungus and fungus gets food from the alga

      • cleaners eat insect pests from the skin of animals (ex: Egyptian plover cleans giraffes and buffaloes)

      • many herbivores such as cows, sheep, deer, horses and rabbits depend on bacteria that live in their stomachs to break down the plant material

    • predator - one eats another (Herbivores eat plants. Carnivores eats animals.)

      • bear eating fish

      • anole eats insect

    • ACTIVITY AND PROCEDURES:
      1.   Place a piece of chalk in pan.
      2.   Using an eyedropper, have one student drop vinegar
           onto the chalk in a constant stream.
      3.   Observe the fizzing on the surface of the chalk
           when the vinegar is dropped.
