Safety –Study your safety quiz. Remember that your most important general
responsibility in the science lab is to keep yourself and others from being injured. You
are responsible for knowing all the safety rules including questions like:

   a. has an injury
   b. breaks something
   c. spills something
   d. all of the above
3. If you don’t understand the instructions for a lab, what should you do?

4. Always wash your hands with ____________, after you complete a lab activity.

   considered a __________________________________.

The Microscope:
19. The short red objective is called the ___________________ objective.
20. The yellow objective is called the _________________ power objective.
21. The blue objective is called the _________________ power objective.

22. Assuming the Magnification of the eyepiece is 10X, the red is 4X, the yellow is 10X
and the blue is 40X, what mathematical formula do you use to calculate the total
magnification of the microscope for each objective:
_____________________________________________________________________
23. Show your calculation for low power and high power using the above information.

_____________________________________________________________________

Ecology:
You are responsible for understanding the following words as well as any other terms
covered in notes, classwork, labs, etc. for this unit. Flash cards are an excellent way
to study vocabulary.

____________________________________________________________________
41.

      Which of these organisms receive the highest percent of energy from the sun?

      How much energy will be available for the secondary consumers in this
      pyramid?

      How much energy is passed on to each trophic level?

      What happens to the energy that is lost?

42.




What is the importance of the fungi (decomposer) in the above food chain?

Would the grasshopper be considered a carnivore, herbivore, omnivore, or
decomposer? Why?

43. What does a pyramid of biomass show?
____________________________________________________________________

46. Identify the type of symbiosis for the examples below.

1.    Bee & Flower: Bees gather nectar from flowers for their
      own use. In moving from flower to flower, bees help these
      plants reproduce by carrying their pollen.

2.    Orchid & Tree: Orchids live in trees. They are self
      sufficient and do not rely on the tree for any nutrients. The
      orchids are protected by the tree’s size and the trees are
      not affected.

3.    Flee & Dog: Fleas feed upon the blood of a dog or other
      animals. The fleas can cause itching and can pass disease.




47.




What type of relationship, between the moose and wolf, is shown in the graph above?

Why did the population of moose increase after 1985?

Why did the population of moose decrease so dramatically after 1995?


48. ECOLOGICAL SUCCESSION The climax community in an area of Arkansas is an
  oak-hickory forest. After the ponds are filled in, the area will undergo another
  series of stages of succession that begins on soil. This is illustrated below.
What is ecological succession?

What type of succession is shown in the illustration?

What types of plants are found in each of the stages of succession shown in the
diagram?

      1.

      2.

      3.

      4.

      5.

What do you call the first species to inhabit the area?




What is a “climax community”?

In Hawaii, new lava flows from the island’s volcano both creates and destroys land.
This leaves new bare rock, void of soil and vegetation. Eventually over time, a new
forest will establish itself. What type of succession is this? How is it different from
secondary succession?
